Yes, of course... I had only "reworked" the 9260 variant yet. You should need
to change it similarly to at91sam9260_devices.c...

Yes it does.

What exactly does "does not boot" mean? No message at all?

Check that your AT91Bootstrap loads u-boot to a sane address not at the very end
of DRAM, and that CONFIG_SYS_TEXT_BASE is exactly the address where AT91Bootstrap
loads u-boot. (I changed AT91Bootstrap to load u-boot to the very begin of DRAM
for our boards.)
