23faf63123 powerpc/mpc5121: fix NULL test in mpc5121_clk_get utility function.
strcmp on NULL results in a segmentation fault, also, remove the second,
redundant test on dev

1879f711d8 powerpc/mpc5121: Add support for CPLD on MPC5121ADS board
Add a interrupt host for the interrupt controller in the mpc5121ads cpld.
PCI interrupts are 0-7 the rest are 8-15 Touchscreen pendown irq is
hardwired to irq1 All other irqs are chained to irq0

fb1803224e powerpc/mpc5121: Add generic board support for MPC5121 platforms
Move shared code from mpc5121_ads.c to new file mpc512x_shared.c
- mpc512x_find_ips_freq -> unchanged
- contents of mpc5121_ads_init_IRQ -> mpc512x_init_IRQ
  - looking for fsl,mpc5121-ipic instead of fsl,ipic
- mpc5121_ads_declare_of_platform_devices -> mpc5121_declare_of_platform_devices
  - and use compatible for lookup instead of node name

Add new generic board setup mpc5121_generic.c

137e95906e powerpc/mpc5121: Add clock driver
Plugs into the generic powerpc clock driver in
arch/powerpc/kernel/clock.c

The following subset of clk_interface is implemented:
    clk_get, clk_put:  get clock via name, release clock
    clk_enable, clk_disable:  enable or disable clock
    clk_get_rate:  get clock rate in Hz
    clk_set_rate:  stubbed
    clk_round_rate:  stubbed
    clk_set_parent: NULL
    clk_get_parent: NULL

d4eac7501f [POWERPC] Remove unused CONFIG_WANT_DEVICE_TREE
CONFIG_DEVICE_TREE was the only user of CONFIG_WANT_DEVICE_TREE but
it was removed in commit id 2543133381
(bootwrapper: Build multiple cuImages).

This removes CONFIG_WANT_DEVICE_TREE from Kconfig and the defconfigs.

e177edcd15 [POWERPC] mpc512x: Basic platform support
512x is very similar to 83xx and most
of this is patterned after code from 83xx.

New platform:
