mkimage has the ability to process two files at the same time. This is necessary for rk356x support as both TPL and SPL need to be hashed individually in the resulting header. It also eases support for rkspi as mkimage handles everything for making the requisite file for maskrom loading.
Add a new flag "separate_files" for mkimage handling to gather the files separately rather than combining them before passing them to mkimage.
Signed-off-by: Peter Geis pgwipeout@gmail.com --- Changelog: v2: I've managed to move this all into mkimage.py as per Alper's suggestion. I've added an example to the readme portion of the function. mkimage,separate_files is now separate-files.
