The following adds local bus, flash and MTD partition nodes for
sbc8548. As well, a compatible field for the soc node, so that
of_platform_bus_probe() will pick it up.
Something that is provided through this newly added epld node
is the Hardware Revision which is now being utilized.

The 8568 MDS needs some configuration changes to the PHY in order to
work properly. These are done in the firmware, normally, but Linux
shouldn't need to rely on the firmware running such things (someone
could disable the PHY support in the firmware to save space, for instance).

The KSI8560 is a single compact, mid-, or full-size Advanced Mezzanine Card
(AdvancedMC™) based on the Freescale™ Semiconductor MPC8560 PowerQUICC III™
microprocessor. This product will serve in data and signaling applications such
as signaling gateways (SGW) and softswitch signaling interface cards.
The board has altera maxii CPLD, that is used to obtain and manage board
configuration. Also there are two SCC UART serial consoles and FCC ethernet,
that is routed to the front panel, while other ethernet controlers (TSEC's) are
routed to the backplane.

* Allow multiple boards to be selected in a single build
* Removed Kconfig option '85xx' which existed only for compat with arch/ppc
* Added a multiplatform 85xx defconfig (mpc85xx_defconfig). This builds
all 85xx boards except sbc8560 and stx_gp3 since these to boards have
board specific ifdef in driver code that may break all other boards

Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data"
and "fsl,qe-ic".
Unfortunately it's still impossible to remove device_type = "qe"
from the existing device trees because older u-boots are looking for it.

This adds the basic support for the Wind River SBC8548 board, implemented
as powerpc. It closely follows the implementation of the MPC8548CDS.

Currently there is no way to disable the CPM2 support. Some boards,
like the SBC8560 have their own external UART and don't have any direct
dependencies on the CPM for a serial console or anything else.

asm-powerpc/mpc85xx.h was really a hold over from arch/ppc. Now that
more decoupling has occurred we can remove <asm/mpc85xx.h> and some of
its legacy.
As part of this we moved the definition of CPM_MAP_ADDR into cpm2.h
for 85xx platforms. This is a stop gap until drivers stop using
CPM_MAP_ADDR.

set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.
To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.
Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).
qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.
