please stop using this PHYS_SDRAM macros. They where replaced by
CONFIG_SYS_SDRAM_(BASE|SIZE).

CONFIG_AT91FAMILY is defined in some asm/arch/hardware.h files. You will
get 'double definition' errors here. The best solution is currently to
include asm/hardware.h in board config right after the correct SoC
define. I have started a discussion on that problem yesterday evening ->

I guess SLOW_CLOCK is missing here ...

just replace the PHYS_SDRAM defines by CONFIG_SYS_SDRAM defines.

I recommend to use SRAM here, see top900(0) header for example.
