I think these are reasonable. > And also for SD fat based images. > "SPL: FIT: Enable SPL_FIT_LOAD for sd bootmode for fat partions" Ug, sorry. You missed the series from Lokesh that added a bunch more features along those lines. I didn't pull them in since it was past the merge window but will for the next release. > Is there any plan to support falcon mode? > Also I see kind of interesting to have one fit image with ATF, Secure > OS, bitstreams and U-Boot and Linux kernel + dtbs > Currently spl_load_simple_fit() seems to me expecting to blindly read > the first fit partition and say this is u-boot and then based > configuration description choose dtb. > > Do you have any plan to get even u-boot image from configurations instead? > The we should get a support for loadables.
