Hi Ron,

I think your change above is right for a MPC8247.

Look at my Patch, which I just posted at linuxppc-dev, which 
(I hope) will help you (!! it is for a MPC8260 based Board):

http://ozlabs.org/pipermail/linuxppc-dev/2005-November/020492.html

or have a look at the Git repository at Denx:

http://source.denx.net/git/linux-2.6-denx.git

where you can find the complete PM82x port for the 2.6.14 Kernel.

Best regards,
Heiko
