Hi Tom,
Yea, I'm not sure if uncompressed ARM32 would work, but I don't believe it was ever working to begin with... as bootz_setup is being called right now ( @ https://source.denx.de/u-boot/u-boot/-/blob/master/common/spl/spl.c#L366 )
My intent was for SPL_OS_BOOT_UNCOMPRESSED to only be used for platforms which need booti_setup (ARM64, ...).
So... I could add a dependency on ARM64 in the config option or I could remove the option altogether and let the booti_setup fail and fallback to bootz_setup. Would either of those work for you?
The code and logic overall needs a bit of refactoring to support "booti", "bootz" and also FIT images. I believe FIT images are how anyone doing falcon mode on arm64 has worked thus far. booti/bootz should only be an option when CMD_BOOTI/Z is set, and FIT should depend on SPL_LOAD_FIT already.
