Spi NAND programmER v.1.0 by McMCC <mcmcc_at_mail.ru>

  Usage:
 -h             display this message
 -d             disable internal ECC(use read and write page size + OOB size)
 -I             ECC ignore errors(for read test only)
 -L             print list support chips
 -i             read the chip ID info
 -e             erase chip(full or use with -a [-l])
 -l <bytes>     manually set length
 -a <address>   manually set address
 -w <filename>  write chip with data from filename
 -r <filename>  read chip and save data to filename
 -v             verify after write on chip

Examples:

1. Get info Flash.
