I think your change above is right for a MPC8247. > Anyone have this working, or any thoughts to contribute? 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.
