Great sounds like a plan. Take a look at the wl12xx patches I posted for
setting up the MMC regulators, that might help with the MMC.
I doubt that the missing PBIAS support is an issue as the eMMC has it's
own fixed regulator.
Then the GPMC patches might do the trick with the OneNAND as there have
been patches posted for various boards for NAND and smc911x.

Yes that's cool.
