[PATCH] powerpc: consolidate mpc83xx platform files
Kim Phillips

Wed Dec 13 04:36:53 EST 2006
Eliminate code redundancy. mpc83[246]x_{mds,itx,sys,pb} files merged
into a single setup.c. machine definitions moved to machdefs.c with
corresponding probe fns. This patch also utilizes of_platform_bus_probe()
in lieu of manually calling of_platform_device_create for each ucc_geth device.
