This driver is incomplete and seriously broken. It can't be enabled
in the Kconfig and it's not even set up to be compiled.
Just remove it.

-Driver: mpc8260cpm
-Description: MPC8260 CPM module generic digital I/O lines
-Devices: [Motorola] MPC8260 CPM (mpc8260cpm)
-Author: ds
-Status: experimental
-Updated: Sat, 16 Mar 2002 17:34:48 -0800
-
-This driver is specific to the Motorola MPC8260 processor, allowing
-you to access the processor's generic digital I/O lines.
-
-It is apparently missing some code.
