We would like to skip the U-boot proper altogether during normal boot of the Flipper One (primarily to trim down the boot time).
U-boot has support for the "Falcon mode" where the U-boot SPL jumps directly to Linux instead of U-boot proper, but there is no known use of that mode on Rockchip SoCs.
We need to figure out a way to produce FIT images with ATF+DTB+Linux instead of ATF+DTB+U-boot (likely extending the binman configuration in mainline U-boot), save pre-configured DTBs and potentially live-patch the preconfigured DTB from SPL with M.2 interface configurations - and document everything.
