Should I also update (in separate patch) at91sam9263ek board
(code is the same there, bad side is - I don't have that board to test)?

I don't understand something here:
- this address is hardcoded in AT91bootstrap (as well as image size - 0x31000),

- I can change it, but it will not boot on "stock" board - should we force
people to recompile AT91bootstrap if they want to use new U-Boot?
or
- Should I add low-level initialization to boot U-Boot from Dataflash
without AT91bootstrap (this is a bit more work)?
or
- There is another way I'm not aware of (perhaps relocate U-Boot in RAM)?
