Hi,
We're going to be using an MPC8255 processor, and I know there are a few
differences between that CPU and the 8260 (e.g. less clock speed, less SCCs,
etc.).
Has anyone run Linux/PPC on an 8255?
What needed to change from the standard 8260 port?
Many thanks in advance,
-elan

We also have custom HW with an MPC8255. PPC Linux 2.4.3 and 2.4.8 runs
perfectly. No changes apart from the things you need to do for custom HW
anyway (IO pinning etc.) were necessary. We also run PPCBoot on the board.
Greetings Michael

I haven't noticed any differences that would affect Linux.

no reports.

Just don't configure the devices that don't exist.
