After just literally falling asleep (laid down, tried to listen to LTT WAN Show and /IMMEDIATELY/ passed out), I am looking at my boot problem again. Apparently, I need to fit a .flt image into the boot partition now - and it's *big.*

The great thing is, I can "think" in the EFI way; most of the boot process is right on my microSD card and it behaves much like an EFI boot; just... smaller. OpenSBI (/dev/mmcblk0p1) -> u-boot (/dev/mmcblk0p2) -> u-boot uEnv + extlinux config + kernel + vmlinz (/dev/mmcblk0p3) -> OS (/dev/mmcblk04)

It's neat. ^^
