[U-Boot] [PATCH 3/7] Add memory test feature for mpc85xx POST.

2010-08-27 Thread York Sun
If enabled in config file and hwconfig, the memory test is performed after DDR initialization when U-boot stills runs in flash and cache. Whole memory is testable. It is mapped 2GB at a time using a sliding TLB window. After the testing, DDR is remapped with up to 2GB memory from the lowest address
