Please do not reinvent the wheel and add yet another meory test. Use one of the existing memory tests we already have - post/drivers/memory.c comes to mind.

That code is not capable of testing more than 2GB of RAM. It assumes that memory has already been initialized, but on PowerPC parts, we only ever map 2GB of DDR. We need a memory test that covers all of DDR, but that requries PowerPC-specific code to create sliding TLB windows during the memory test.
