Anyway, as I said, if you need help or thoughts, feel free to poke me or
our Mailing list, we are surely interested to also have boot support
There currently is a MMC driver being written and submitted (already) to
the lkaml etc that should help you out a lot. MMC support is maybe

its the main way to boot with our u-boot). SPI i'm working on right now,
gotta find a way though to hook up an SPI flash module. Nand is very
very much WiP.
As for initing of DRAM, that's a horrible affair and i've been putting
off refactoring that, afraid things may break if things are even in the
wrong order. The code is a GPL donation from allwinner and based of
their GPL boot0/boot1 code.
