This is a driver for the FIFO device on the LocalPlus bus on an mpc5200 system.
The driver supports programmed I/O through the FIFO as well as setting up DMA
via the BestComm engine through the FIFO.

This patch adds board support for the Media5200 platform. Changes are:
- add the media5200 device tree
- add the media5200 platform support code and cascaded interrupt controller
- add media5200 to the build targets.
Note: this patch also includes a minor tweak to the lite5200(b) target
images list to add the .dtb files to the image list.

This patch adds IRQ controller support to the MPC5200 General
Purpose Timer (GPT) device driver. With this patch the mpc5200-gpt
driver supports both GPIO and IRQ functions.
The GPT driver was contained within the mpc52xx_gpio.c file, but this
patch moves it out into a new file (mpc52xx_gpt.c) since it has more
than just GPIO functionality now and it was only grouped with the
mpc52xx-gpio drivers as a matter of convenience before. Also, this
driver will most likely get extended again to also provide support
for the timer function.
Implementation note: Alternately, I could have tried to implement
the IRQ support as a separate driver and left the GPIO portion alone.
However, multiple functions of this device (ie. GPIO input+interrupt
controller, or timer+GPIO) can be active at the same time and the
registers are shared so it is safer to contain all functionality
within a single driver.

This patch adds support for 'mpc5200-simple-platform' compatible
boards which do not need a platform specific setup. Such boards
are supported assuming the following:
- GPIO pins are configured by the firmware,
- CDM configuration (clocking) is setup correctly by firmware,
- if the 'fsl,has-wdt' property is present in one of the
gpt nodes, then it is safe to use such gpt to reset the board,
- PCI is supported if enabled in the kernel configuration
and if there is a PCI bus node defined in the device tree.

Low-power mode implementation for Lite5200b.
Some I/O registers are also saved here.
A recent U-Boot that supports this (lite5200b_PM_config) is needed.

Implement deep-sleep on MPC52xx.
SDRAM is put into self-refresh with help of SRAM code
(alternatives would be code in FLASH, I-cache).
Interrupt code must also not be in SDRAM, so put it
in I-cache.
MPC52xx core is static, so contents will remain intact even
with clocks turned off.

The efika platform used three files efika-pci.c efika-setup.c and
a 2 line efika.h to link the two. The total of code in those is
really not much and therefore, I think they're better merged
in a single file.
There is absolutely _no_code_change_ at all, just merged the files.

The Efika board isn't different enough from other 52xx based boards to
