Excellent!

I still lack A10 hardware to try things out on, or any documentation on
the DDR initialization part.

The I/O multiplexer setup seems pretty simple, assuming documentation is
reasonably correct on which bits are for which functions.

Luke, what is the status on the development boards?

Still looing for a suitable tablet for hacking on. As I am not planning
to using it as a development platform more RAM is premium and of the A10
tables I have found only Novo 7 ELF seem to be equipped with 1GB, and
the ELF seems to be hard to get hold of over here. Also not 100% sure
how one forces FEL mode on a A10 tablet if the NAND boot-loader gets
fucked.

Maybe it's sufficient to insert a bootable SDCARD with recovery in such
case. CARD0 has priority over NAND, right?
