BAREBOX_INJECT_PATH is a ':' separated path, so expanding it like this doesn't work anyways. So in general I've been thinking which parts make sense in PTXdist upstream and which parts should be in the BSPs. I mean it doesn't really scale, if we add firmware files for all boards into PTXdist upstream. So I had the vague idea that we could add files that are SoC specific to PTXdist and leave the board specific files in the BSP. Then I saw this: > +BAREBOX_INJECT_FILES += rk3568_ddr_1560MHz_v1.08.bin:arch/arm/boards/rockchip-rk3568-evb/sdram-init.bin My understanding was that this file is the code that does the SDRAM timing calibration. So I expected it to be SoC specific and therefore in a more generic path, not the board directory. Am I missing something here? > +BAREBOX_INJECT_FILES += rk3568_bl31_v1.24.elf:firmware/rk3568-bl31.bin That's TF-A right? > +BAREBOX_INJECT_FILES += rk3568_bl32_v1.05.bin:firmware/rk3568-op-tee.bin I expected these files to be board specific, but they are in a generic directory? Also, I would expect those to be built from source. And about the suboptions: Do we actually need them? I mean, if we copy a few extra files, then barebox will just ignore them, right?
