/**
* @file
* @brief convert a barebox image for SPI loading on AM35xx
*
* FileName: scripts/mk-am35xx-spi-image.c
*
* Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
* a special format:
*
* - 32 bit image size in big-endian
* - 32 bit load address in big-endian
* - binary image converted from little- to big-endian
*
* This tool converts barebox.bin to the required format.
