There's a trend to solve everything in python. Don't have knowledge about python, but there's a 3rd image format for NAND [1]. Could someone advise how to fit the extra XXX padding option in the mkimage.py file? (Simon ?)
Binman's mkimage support is mostly a wrapper around the mkimage executable, so that patch would need to be applied first. Assuming you want to run something like the example in that patch:
mkimage -n rk3066 -T rknand -d <tpl>:<spl> -X 16384,1 <out>
I think you'd only need something like the first patch of this series for binman to get the multiple inputs working, and I expect a binman dtb fragment like the following would then work for the above command:
mkimage { args = "-n", CONFIG_SYS_SOC, "-T", "rknand", "-X", "16384,1";
u-boot-tpl { };
u-boot-spl { }; };
Could someone from Rockchip give info on whether the SD or SPI image format has similarity to the NAND image format to reuse code? (Kever ?)
Missing are u-boot documents on Rockchip file formats itself other then reading the /tools/rkxxx.c code.
(I don't know the formats' details, so can't comment on those.)
Currently there's a small section about rkimage, rksd and rkspi in README.rockchip. Move that to rockchip.rst as well when busy with image formats in this serie?
