I forgot to rephrase the commit log. As seen in patch 1/8, there 
actually doesn't seem to be a need for rksd for passing multiple data 
files to mkimage, only the TPL could be passed to mkimage and SPL 
appended right after that blob generated by mkimage. Maybe it's luck but 
it seems to work for me the few tries I did on SD card and eMMC.

Not sure this fits the "Relationship to mkimage" section in binman.rst? 
What part of the logic exactly would you like to move from mkimage to 
binman?

Cheers,
