[PATCH] powerpc: consolidate mpc83xx platform files
Kim Phillips
kim.phillips at freescale.com
Sat Dec 9 12:07:58 EST 2006
Eliminate code redundancy. mpc83[246]x_{mds,itx,sys,pb} files merged
into a single setup.c. machine_probe, instead of using the model property,
checks the compatible property for "MPC83xx" (dts files updated appropriately).
This patch also utilizes of_platform_bus_probe() in lieu of manually
calling of_platform_device_create for each ucc_geth device.
