[U-Boot] at91sam9263ek version

[Uli Raich]

Hi all,
I just sent patches for the at91sam9263ek version based on the rework110218 branch of the u-boot-atmel rework.
This is the first time I send patches to the list. So... please bare with me if I did something wrongly.
The only board I have to test things on, is an armputer-vmax board from a young polish company creotech. This board is very similar to the at91sam9263ek board but there are a few differences (e.g. the LEDs are connected differently and the quartz frequency is different). Therefore I am not really sure that the patches will be all ok for the at91sam9263ek board. If somebody who has the atmel board would check? I have deleted the  at91sam9263ek_dataflash_cs0 configuration from the Makefile and added the configuration into boards.cfg. I also added a config for the armputer-vmax.
I had a problem that gd->ram_size was not set up, which made the program crash. I initialized this in dram_init for the board but maybe this should be done differently. I am also not really sure about the naming conventions in the include/configs file for the board.
