I reread the sentence, and I am really describing what SPL alone does, not Falcon mode. SPL is already available for different storage and there are some boards booting from SD. Check for CONFIG_SPL_MMC_SUPPORT in include/configs, there are plenty of boards using it. On the other side, Falcon Mode (SPL + CONFIG_SPL_OS_BOOT) is set only for two boards, twister and devkit8000, bpth booting from NAND.
