Hi,
I think there's something wrong with the implementation distinction of SPL_FIT and SPL_LOAD_FIT.
CONFIG_SPL_FIT: * Support Flattened Image Tree within SPL CONFIG_SPL_LOAD_FIT: * This option instead enables generation of a FIT (Flat Image Tree) which provides more flexibility.
I would expect that enabling SPL_FIT _alone_ will allow SPL to load FIT images. However, that's not what the code implements:
common/spl/spl_mmc.c: int mmc_load_image_raw_sector(...) { if (IS_ENABLED(CONFIG_SPL_LOAD_FIT) && image_get_magic(header) == FDT_MAGIC) {
In order to "Support Flattened Image Tree within SPL" we actually need to enable SPL_LOAD_FIT. This has the side effect of making the u-boot image a FIT, which we may or may not want. I think the correct code should say:
if (IS_ENABLED(CONFIG_SPL_FIT))
Is this something that was overlooked (for so many years)? Is there something I'm missing?
