From: Grant Likely grant.lik...@secretlab.ca
The PCI device tree scanning code in pci_64.c is some useful functionality.
It allows PCI devices to be described in the device tree instead of being
probed for, which in turn allows pci devices to use all of the device tree
facilities to describe
consolidation there.
I agree, but I'll do those things in a separate patch. I'm making as
few code changes as possible in this patch to ease review.

I'm pretty sure nobody has done a Linux port to any of these chips.
Nor do I know of any work having been done in the past.

Here are some OF and MPC5200 changes needed for 2.6.32. Mostly
defconfig updates

phy driver doesn't work for you, then yes, add a new micrel driver.
To hook it up to the MPC5200 FEC, you just need to have the correct

refactor the driver until I'm certain of the direction that things are

ignore them. Until the bulk of the out-of-tree 5121 support is
merged, it would be helpful to specifically mention in the patch
description whether or not it should be merged upstream.

I saw that Grant Likely is doing updates to all of the of_* stuff right now,
would it be ok to have these routines here, renamed as dlpar_*, and look
to merge them in with Grant's updates when he finishes?
