Possible improvement:  When you figure the devices behind the pxb are
not initialized by the firmware (i.e. unmapped), you can try grab some
address space not used by devices under root bus 0 and assign it to the
pxb.  Then the linux kernel can initialize the devices even if the
firmware did not.

[ Surely should be done incremental like hotplug support to not delay
  this series even more ]
