look at a 2.6.22-rc1 kernel to see how this has changed. It also
effects the .dts interrupt numbers. Please match how the mpc8641hpcn
does things.

This is mostly redundant with the basic show cpu info, do you need
your own?

the check you have is too generic, you probably need something more

The plan is to add code to read the EEPROM device and show more info.

I was a little concerned when I saw a hard-coded address. I never would
have found the conflict with the QUAD PHY (it starts at 0x1f and increments
for each device) without your help.
Let me know what you think and I'll put something together.

You may want to think about having both core's in the .dts and build
with !CONFIG_SMP for single and CONFIG_SMP for dual.

Noticed you didn't have an PCIe support. Is that something that
exists on the board? is wired to anything?

I'll talk to someone here and see. I think a simple thing would be
to make it a Kconfig'ble option to what the value is for TBIPA_VALUE
and default to 0x1f but changeable in your defconfig.
