Yeah, that's it.

Looks like your config ends up waiting for root on the mmc. But we're missing
what was board-n800-mmc.c, so that needs to be updated for mainline.
You can find the old code in the omap-2.6.30 branch under arch/arm/mach-omap2
if you have the cycles to update it.

Also, the drivers/cbus needs to be updated to get the GPIO pins from
board-*.c files, otherwise the retu watchdog will power down the system
in 30 seconds.

Those should be just fine.

Yeah, that's needed only for the serial console.
