This patch removes some functionality from at91rm9200ek board but the remaining functionality does now work with newer at91 code and arm-relocation. Currently missing features are: - dataflash booting (due to missing HW for testing) - MMC/SD-Card - first stage bootloader support is completely removed (not needed for NOR) Cause this board was (some days ago) reference for all at91rm9200 based boards this should be a good starting point to convert all remaining at91rm9200 borads to at91 code. Aside from that this is a good base to get some drivers between at91sam/at91rm/avr32 merged.
