I'd prefer one big patch, assuming it is almost ready to roll into the tree. Chances ate I'll be committing it. Bit there might also be a second effort that has patches in flight too. There was some talk too of investgating fdt to cope with the different families. Btw, when I was doing the original port I found the multiplexed pins were rarely configured by the wide array of boot loaders... You were lucky if the memory and nic pins were configured.
