Rockchip-based Chromebooks support booting from SPI flash. It is annoying to have to manually build the SPI image when the SD image is built automatically.
This feature is already available for x86 devices, so the existing mechanism is reused. Briefly, this allows a BUILD_ROM environment variable to be provided to indicate that any required binary blobs are present and it is safe to build the ROM.
A new 'mkimage' type is added to binman to support building binaries with mkimage with a binman definition. This avoids Makefile/shell/Python code to do the same thing.
This series uses binman to produce a ROM image on two selected Chromebooks, Bob (RK3399) and Jerry (RK3388).
