1/3 can be ignored. After some more testing it was determined using DMA to initialize memory was slower than the original method. 2/3 is up to Kim, but its not really necessary. Right now the 83xx boards are hard-coded to initialize memory with the value of 0xdeadbeef. The change was intended to make the init value configurable based on CONFIG_MEM_INIT_VALUE like the MPC85xx/86xx arches. Let me know if you'd like me to resend Kim - the current patch would need to be rebased/updated. 3/3 is no longer needed. The change was rolled into a resubmission of a different patch I believe. I won't take any action unless Kim is interested in 2/3.
