Thanks, I saw you committed part of the stuff I provided to the AT91
branch.

FYI: Your patch to at91rm9200dk, disabling the dataflash is wrong.
There is a 2 MB NOR flash *and* an 8 MB Dataflash on that board.
There is also a card connector allowing you to add an 
8 MB dataflashcard as well.

The default operation of the board is to boot from the NOR
flash, but you can remove a resistor to allow booting 
from the dataflash.

This is how my at91rm9200dk is configured.
solderpads are even gone,so no way back to the parallel boot...
There is also a card connector allowing you to add an 
8 MB dataflashcard as well.


The lack of a jumper was one of deficiencies
that made Atmel redesign the board to the more
modern AT91RM9200EK where you have a jumper to
select between booting from parallel flash 
(by setting BMS: Boot Mode Select) low
and booting from the dataflash by setting the BMS pin high.

Most people I know of uses the AT91RM9200 with dataflash
so the support for the at91rm9200df board would be real nice
to have added ASAP.
