Xenomai on i.MX ARMv7 Platform

Description

Xenomai is real-time framework, which can run seamlessly side-by-side Linux as a co-kernel system. This a porting for i.MX

How to build

copy xenomai-arm to /sources/meta-imx/meta-bsp/recipes-kernel, add the following variable in conf/local.conf before build xenomai by command bitake xenomai.

XENOMAI_KERNEL_MODE = "cobalt"

IMAGE_INSTALL_append += " xenomai"

DISTRO_FEATURES_remove = "optee"

or XENOMAI_KERNEL_MODE = "mercury"

IMAGE_INSTALL_append += " xenomai"

DISTRO_FEATURES_remove = "optee"

If XENOMAI_KERNEL_MODE = "cobalt", you can build dual kernel version. And If XENOMAI_KERNEL_MODE = "mercury", it is single kernel with PREEMPT-RT patch.
