[PATCH 1/2] Added support for PRTLVT based boards (MPC5121)
Made MPC5121_ADS board support generic:
Renamed arch/powerpc/platforms/512x/mpc5121_ads.c and added list of supported
boards.
For both MPC5121 ADS or PRTLVT support, just select MPC5121_GENERIC and use
the corresponding device-tree.

Re: [PATCH 1/2] Added support for PRTLVT based boards (MPC5121)
Looking even better. Just a few more comments. I'll probably be able
to pick up the next one for inclusion in 2.6.27.

There should probably be a node to describe the local bus that the
flash is attached to and this flash node should be a child of the bus.

I'm still not all that keen on encoding the partition information into
the 'stock' device tree included with the kernel as it is more of a
configuration description that is more properly supplied by the
bootloader. This is a debate that has been going back and forth over
the last few months, so there isn't a solid concensus yet, but my
preference is to remove or comment out the partition information for
now.

(nitpick) There is a recommended practice that says node names should
be generic as much as possible, so I think this should probably be
[EMAIL PROTECTED] The compatible value is fine.

If this is a video display device, the recommended generic name is
[EMAIL PROTECTED], not [EMAIL PROTECTED].
