Anatolij Gustschin 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.

Anton Vorontsov e2801806de powerpc/fsl_soc: isolate legacy fsl_spi support to mpc832x_rdb boards
The advantages of this:
- Don't encourage legacy support;
- Less external symbols, less code to compile-in for !MPC832x_RDB
  platforms.

Anton Vorontsov 364fdbc00f spi_mpc83xx: rework chip selects handling
The main purpose of this patch is to pass 'struct spi_device' to the chip
select handling routines.  This is needed so that we could implement
full-fledged OpenFirmware support for this driver.

While at it, also:
- Replace two {de,activate}_cs routines by single cs_contol().
- Don't duplicate platform data callbacks in mpc83xx_spi struct.

Timur Tabi 43c9f43492 powerpc: remove support for bootmem-allocated memory for the DIU driver
Early versions of the Freescale DIU framebuffer driver depended on a bootmem
allocation of memory for the video buffer.  The need for this feature was
removed in commit 6b51d51a, so now we can remove the platform-specific code
that allocated that memory.

Suspend-to-RAM is implemented as "deep sleep" (with the processor
turned off) on 831x.

Kumar Gala e1c1575f83 [POWERPC] 85xx/86xx: refactor RSTCR reset code
On the majority of 85xx & 86xx we have a register that's ability to
assert HRESET_REQ to reset the board.  We refactored that code so it
can be shared between both platforms into fsl_soc.c and removed all
the duplication in each platform directory.

Vitaly Bordug fba4366536 POWERPC: Add cpm2 stuff support to the fsl_soc.c
This patch contains necessary modifications to support the CPM2 SoC peripherals.
For the time being, those are fs_enet Ethernet driver and cpm_uart serial.
Written initially to support mpc8560, it also suites to the part of the large PQ2
(more specifically, mpc8260) family.

Kumar Gala eed3200108 [PATCH] powerpc: Add FSL SOC library and setup code
Parse the flat device tree for devices on Freescale SOC's that we know
about (gianfar, gianfar_mdio, i2c, mpc83xx_wdt).  We need to setup
platform devices and platform data for these devices to match arch/ppc
usage.

Also add a helper function (get_immrbase) that reports the base
address of the MMIO registers on the SOC.
