This adds support for relocation, but won't work for the default settings whereas AT91Boot loads u-boot to the last meg and it then tries to relocate slightly later, thus overwriting itself.

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 -> http://article.gmane.org/gmane.comp.boot-loaders.u-boot/97903

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.
