fpsoc-sdk

1.OS支持说明

本SDK在以下环境中进行过编译测试:

Ubuntu 18.04

Ubuntu 20.04

Ubuntu 22.04

Ubuntu 23.04

2.编译步骤

  1. 获取SDK

    如果是以git方式下载SDK,则直接执行:

    git clone xxxxx/sdk.git --recurse-submodules
    cd sdk
    git submodule update --init --recursive
    

    如果获取到的源代码为压缩包形式,则为SDK创建一个新的目录,并进入该目录:

    mkdir sdk
    cd sdk
    

    解压缩SDK软件包到当前目录:

    tar -xzvf sdk.tar.gz
    

    SDK压缩包中并未包含工具链,相应工具链需要单独获取。

  2. 如果是通过git方式下载的SDK源代码,并且源代码目录下已经存在toolchains/setup.sh脚本,则在编译sdk时会自动进行toolchain的setup,无需再进行工具链配置。

    否则需要在SDK目录下创建toolchains目录,并确保:

    arm64 linux的编译器位于路径:"toolchains/aarch64-linux/bin/aarch64-linux-gnu-gcc";

    arm64 baremetal的编译器位于路径:"toolchains/aarch64-bm/bin/aarch64-none-elf-gcc";

    riscv64 linux的编译器位于路径:"toolchains/riscv64-linux/bin/riscv64-unknown-linux-gnu-gcc";

    riscv64 baremetal的编译器位于路径:"toolchains/riscv64-bm/bin/riscv64-unknown-elf-gcc"。

  3. 如果是首次编译,需要执行这两个命令安装编译环境所需的软件(针对ubuntu):

    sudo apt-get update
    sudo apt-get install make gcc g++ flex bison u-boot-tools liblz4-tool libncurses5-dev
    
  4. 执行下面的命令,选择您的芯片型号,例如"1. anlogic_dr1m90":

    source ./envsetup.sh
    
  5. 如果该SDK软件包只支持一个芯片型号时,将不会打印菜单供您选择,系统会直接使用该芯片型号。

  6. 执行下面的命令,选择您所需的Board配置,例如"ad101v20_ad103v20-tf-openamp-rtlinux":

    ./build.sh lunch
    
  7. 执行下面的命令,编译固件:

    ./build.sh all
    

    编译生成的固件在"device/output/anlogic_dr1m90/image/"目录下;需要烧到flash的image文件在"device/output/anlogic_dr1m90/genimage/"目录下。

  8. 如果需要编译32位用户空间系统,需要确保arm32 linux的编译器位于路径:"toolchains/aarch32-linux/bin/arm-linux-gnueabihf-gcc";并修改对应板级配置文件中的"ANLOGIC_BUILDROOT_DEFCONFIG",例如device/anlogic_dr1m90/BoardConfig-ad101v20_ad103v20-tf.mk,修改为:

    export ANLOGIC_BUILDROOT_DEFCONFIG=anlogic_dr1m90_linux32_defconfig
    

    如果已经编译过64位系统,则需先运行./build.sh cleanbuildroot,然后按上面的步骤正常编译。

3.更新PL bitstream并生成BOOT.bin固件

  1. 执行下面的命令,选择您的芯片型号,例如"1. anlogic_dr1m90":

    source ./envsetup.sh
    
  2. 执行下面的命令,选择您所需的Board配置,例如"ad101v20_ad103v20-tf":

    ./build.sh lunch
    
  3. 将TD生成的bit文件保存到device/anlogic_dr1m90/bitfiles目录下,例如demo_20240820.bit

  4. 打开Bootgen配置文件device/anlogic_dr1m90/bif/boot-apu-evb.bif,确保load pl段未被注释

  5. 打开Board配置文件device/anlogic_dr1m90/BoardConfig-ad101v20_ad103v20-tf.mk,将变量"ANLOGIC_BIT_IMAGE"改成相应的bit名,例如:

    export ANLOGIC_BIT_IMAGE=device/anlogic_dr1m90/bitfiles/demo_20240820.bit
    

    如采用hpf中的bitstream,则注释该变量,例如:

    #export ANLOGIC_BIT_IMAGE=device/anlogic_dr1m90/bitfiles/demo_20240820.bit
    

    如果不想使用任何bitstream,则可以设置:

    export ANLOGIC_BIT_IMAGE=NO
    
  6. 执行下面的命令,生成BOOT.bin:

    ./build.sh bootgen
    

    生成的BOOT.bin在device/output/anlogic_dr1m90/image/目录下。

    生成的镜像在device/output/anlogic_dr1m90/genimage/目录下。

  4. 通过openocd将镜像烧录进nor flash,系统启动

    flash默认布局如下:

    mtdparts=alspinor:8M(boot),128k(scr),128k(env),128k(dtb),8M(kernel),-(rootfs)
    
        0x000000     -    0x800000     8M      BOOT.bin
        0x800000     -    0x820000     128K    scr
        0x820000     -    0x840000     128K    env
        0x840000     -    0x860000     128K    dtb
        0x860000     -    0x1060000    8M      kernel
        0x1060000    -                         rootfs
    

7.编译emmc fat启动固件

  1. 执行下面的命令,选择您的芯片型号,例如"1. anlogic_dr1m90":

    source ./envsetup.sh
    
  2. 执行下面的命令,选择您所需的Board配置,例如"ad101v20_ad103v20-emmc1-fat":

    ./build.sh lunch
    
  3. 执行下面的命令,生成镜像:

    ./build.sh all
    

    生成的镜像在device/output/anlogic_dr1m90/genimage/目录下。

  4. 通过openocd将镜像烧录进emmc,系统启动

    emmc默认布局如下:

    32k(分区表),32M(fat),128M(rootfs),-(usrfs)
    
        0x000000     -    0x8000       32K     分区表信息
        0x8000       -    0x2008000    32M     BOOT.bin、dtb.bin、kernel.bin
        0x2008000    -    0xA008000    128M    rootfs(ext4)
        0xA008000    -                         userfs(ext4)
    

8.将自己的文件打包进rootfs

  1. 将需要打包的文件放到一个目录中,目录内部的路径按照rootfs中期望的路径进行组织。

  2. 在板级配置文件例如"BoardConfig-ad101v10-tf.mk"中配置ANLOGIC_EXTRA_ROOTFS_DIR变量,指向需要打包的目录。指定的路径需要是绝对路径。

  3. 执行下面的命令,重新编译rootfs:

    ./build.sh buildroot
    
  4. 打包目录下的内容更新后,只需执行"./build.sh buildroot"即可,重新生成的rootfs会包含这些内容更新。

9.linux下更新PL bit

  1. 编写dts文件如下,例如文件名为test.dts。示例中的码流文件为led_cnt.bit,可以改成自己码流文件的名字。

    /dts-v1/; 
    /plugin/; 
    / {
        fragment@0 {
            target-path = "/soc/base_fpga_region";
            #address-cells = <0x2>;
            #size-cells = <0x2>;
            __overlay__ {
                #address-cells = <0x2>;
                #size-cells = <0x2>;
                firmware-name = "led_cnt.bit";
                config-complete-timeout-us = <3000000000>;
            };
        };
    };
    
  2. 运行如下命令,将会生成test.dtb文件:

    dtc -I dts -O dtb -o test.dtb test.dts
    

    如果没有dtc命令,则进行安装:

    sudo apt-get install device-tree-compiler
    
  3. 执行如下命令进行fpga配置

    mkdir -p /lib/firmware
    cp -vf test.dtb /lib/firmware/
    cp -vf led_cnt.bit /lib/firmware/
    mount -t configfs none /sys/kernel/config
    mkdir /sys/kernel/config/device-tree/overlays/0
    echo test.dtb > /sys/kernel/config/device-tree/overlays/0/path
    
  4. 如果需要重新配置,则需先执行如下命令,然后再执行步骤3)

    rmdir /sys/kernel/config/device-tree/overlays/0
    
  5. 如需对bit文件进行加密验签等,则需要制作一份bif文件,该bif文件只包括bit文件。加密验签的key必须和生成BOOT.bin时使用的key一致。然后运行下面的命令,生成加密或者签名后的bit文件:

    ./build.sh albg xxxx.bif
    

    之后,再按前面的步骤进行PL bit下载。

10.linux下解析hpf生成fsbl、并替换bitfile用于生成BOOT.bin

  1. 以dr1m90为例,将hpf文件保存到device/anlogic_dr1m90/hpf/目录下

  2. 执行下面的命令,选择anlogic_dr1m90:

    source ./envsetup.sh
    
  3. 执行下面的命令,选择所需的Board配置:

    ./build.sh lunch
    
  4. 修改对应的"BoardConfig-xxx.mk"中ANLOGIC_HPF变量内容为指定的hpf

  5. 注释对应的"BoardConfig-xxx.mk"中ANLOGIC_FSBL_IMAGE、ANLOGIC_BIT_IMAGE变量

  6. 打开Bootgen配置文件"device/anlogic_dr1m90/bif/boot-apu-evb.bif",确保load pl段未被注释

  7. 执行下面的命令,编译master_sdk中的fsbl工程:

    ./build.sh fsbl
    
  8. 执行下面的命令,生成BOOT.bin:

    ./build.sh bootgen
    

11.board config配置

ANLOGIC_ARCH: 系统架构,riscv或者arm64

ANLOGIC_TARGET_PRODUCT: chip型号,例如:dr1m90和dr1v90

ANLOGIC_OPENSBI_JUMP: opensbi结束后的跳转地址

ANLOGIC_TOOLCHAIN: 编译SDK时使用的工具链的路径

ANLOGIC_TOOLCHAIN_FSBL: 编译fsbl时使用的工具链的路径

12.镜像文件

sd卡启动时,启动镜像生成在"device/output/chip型号/image/"路径下:

BOOT.bin: 启动文件,包含fsbl和uboot镜像,如果是riscv则还包含opensbi镜像

boot.scr: uboot启动脚本

kernel.bin: linux内核镜像文件

rootfs.bin: rootfs镜像文件

dtb.bin: linux内核的设备树镜像

如果是从nor/emmc/nand等flash启动,则会将这些镜像文件打包生成烧录镜像, 存放在"device/output/chip型号/genimage"路径下

例如:

mmc_fat_image.bin: 原始的烧录镜像文件

mmc_fat_sparse.bin: sparse格式的烧录镜像文件,相对原始烧录镜像尺寸会变小。

13.linux dts结构

anlogic-dr1m90-ad101-v20.dts  (针对ad101-v20板级dts,包含ddr、led、key、serial、i2c、usb、gbe等外设打开或关闭)
├── anlogic-dr1m90.dts  (各外设clock等信息)
│   ├── anlogic-dr1m90.dtsi  (各外设设备节点名称、基地址、中断号等信息)
│   └── anlogic-dr1m90-plat.h  (默认参数配置)
│       └──anlogic-dr1m90-hpf.h  (参数从hpf导入)
└── anlogic-dr1m90-softip.dts  (softip相关dts配置,默认从hpf导入)
                               (如需自定义softip dts在device/anlogic_dr1m90/Config.mk中开打变量ANLOGIC_BIT_SOFTIP_DTS)

anlogic-dr1m90-ad101-v20-qt.dts  (qt对应dts,包含hmdi、dma、i2c信息)
└── anlogic-dr1m90-ad101-v20.dts

14.soft reboot

soft reboot是在不reset hardware的情况下实现重新加载OS并重启的功能。

测试步骤如下:

  1. 修改dts,为u-boot保留内存。例如:

    &reserved_memory {
    	ubmem: ubmem {
    		no-map;
    		reg = <0x0 0x200000 0x0 0x200000>;
    	};
    };
    
  2. 修改dts,打开watchdog0,并且设置模式为irq模式,例如:

    &watchdog0 {
    	status = "disabled";
    	rmod = <2>; // RMOD_RESET = 1, RMOD_IRQ = 2
    	status = "okay";
    };
    
  3. 运行./build.sh kernelmenuconfig,打开CONFIG_ANLOGIC_SOFT_REBOOT

  4. 编译并启动linux,使用sdk/app目录下编译出的memtool工具将编译好的u-boot.bin加载到0x200000处,然后运行sdk/app目录下编译出的wdt_test程序。

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.
