I am booting over tftp with nfs mounted root already. I executed the command
you provided at the console with no matches. I noted that the highest memory
address tested was ffffff which makes sense considering the system has 16 MB
RAM. Here is my physical memory map:
0x0 - 0xfffff : SDRAM
0x8000000 - 0x83FFFFF : Flash
0x9000000 - 0x90FFFFF : FPGA
0xEF600000 - 0xEFFFFFF : PPC405GP memory mapped registers
0xFFE00000 - 0xFFFFFFFF : BootPROM

Does this help?

Thanks again,
