[U-Boot] support all dataflash for at91sam9g20ek_2mmc

[John Stile <john@stilen.com>]

I am using uboot-2013.01, with at91sam9g20ek_2mmc and I am trying to
build for dataflash, using at91bootstrap-1.16, and buildroot-2011.11

Initially I built for nand flash, with a patch to boards.cfg and
at91sam9260ek.c

This was fine if I used the reset button, but from a cold boot, startup
stopped after after at91bootstrap-1.16, and uboot never starts.

Now I am trying to build uboot for all dataflash, but I still see the
same behavior with uboot.

Uboot worked from dataflash when using uboot-1.3.6 (and patches from
atmel), but much has changed since then, so it is hard to figure out if
something from those patches is lost in the current uboot.  

What can I try next.

Bellow are the patches I applied so far.

boards.cfg: add target name
at91sam9g20ek_2mmc_nandflash,at91sam9g20ek_2mmc_dataflash_cs0,at91sam9g20ek_2mmc_dataflash_cs1
