Which patch? Valentine's or mine under the subject? Don't know about the
former, but mine patch is pretty obvious: your commit
5bece127f0666996ca90772229e00332a34e516c moved PCI nodes out of soc node,
but you forgot to change regs = <>, thus instead of e000a000/e0008000,
kernel used a000/8000 for accessing PCI ccsr registers.
