Several functions are only ever referenced locally, so make them static.
Of those functions, many of them are protected by an #if. However, the
code which can compile fine in either case.
Now that (1) the unneeded code is marked 'static' and (2) the code is
only used under a C 'if (IS_ENABLED(CONFIG_FB_FSL_DIU))', the compiler
can automatically remove the unneeded code, and we don't need the #if or
the empty stub functions.

Instead of using ill-defined numbers (0, 1, and 2) for the monitor port, allow
the user to specify the port by name ("dvi", "lvds", or "dlvds"). This works
on the kernel command line, the module command-line, and the sysfs "monitor"
device.
Note that changing the monitor port does not currently work on the P1022DS,
because the code that talks to the PIXIS FPGA is broken.

Add functions to restart and halt the current partition when running under
the Freescale hypervisor. These functions should be assigned to various
function pointers of the ppc_md structure during the .probe() function for
the board:
ppc_md.restart = fsl_hv_restart;
ppc_md.power_off = fsl_hv_halt;
ppc_md.halt = fsl_hv_halt;

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.

The advantages of this:
- Don't encourage legacy support;
- Less external symbols, less code to compile-in for !MPC832x_RDB
platforms.

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.

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.

Basic PM support for 83xx. Standby is implemented as sleep.
Suspend-to-RAM is implemented as "deep sleep" (with the processor
turned off) on 831x.

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.

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.

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.
