You're on the right track.  Earlier on I started calling
barebox_arm_entry(0x10000000 + 0x800000, SZ_1G, fdt), because otherwise
it would fail in mysterious ways.  Now that I've got ram passing working
correctly, I've set it back to 0x10000000, and I'm able to get further.
 I've also increased the MALLOC_SIZE from 8MB to 64MB, which has made
some out-of-memory errors go away.

Now, it gets much further, even with CONFIG_MMU_EARLY enabled.  Now it
crashes with an error that I see SabreSD was getting at one point, but
I'm not sure how they resolved it:

### ERROR ### Please RESET the board ###

It's nice to see a USB error message in there -- it makes me think the
two problems might be related.  However, USB still doesn't work with the
MMU disabled, even after fixing the RAM addresses.
