6baf11906e powerpc/512x: don't compile any platform DIU code if the DIU is not enabled
If the DIU framebuffer driver is not enabled, then there's no point in
compiling any platform DIU code, because it will never be used.  Most of
the platform code was protected in the appropriate #ifdef, but not all.
This caused a break in some randconfig builds.

This is only a problem on the 512x platforms.  The P1022DS and MPC8610HPCD
platforms are already correct.

This patch reverts commit 12e36309f8 ("powerpc:
Option FB_FSL_DIU is not really optional for mpc512x") and restores the
ability to configure DIU support.

4b5006ec7b powerpc/5121: shared DIU framebuffer support
MPC5121 DIU configuration/setup as initialized by the boot
loader currently will get lost while booting Linux. As a
result displaying the boot splash is not possible through
the boot process.

To prevent this we reserve configured DIU frame buffer
address range while booting and preserve AOI descriptor
and gamma table so that DIU continues displaying through
the whole boot process. On first open from user space
DIU frame buffer driver releases the reserved frame
buffer area and continues to operate as usual.

284ed66fc3 powerpc/mpc5121: avoid using arch_initcall for clock init
Move mpc5121_clk_init() call to platform init code so it won't
get called on non-5121 platforms on a multiplatform kernel.

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
