CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
really meaningful anymore. It was basically equivalent to PPC64 || 6xx.
This removes it along with the following changes:
- 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
on 6xx which is what they want anyway.
- A new symbol, PPC_BOOK3S, is defined that represent compliance with
the "Server" variant of the architecture. This is set when either 6xx
or PPC64 is set and open the door for future BOOK3E 64-bit.
- 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
PPC64 && PPC_BOOK3S
- A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
used to control the use of prom_init.c

Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).
Part 5 of 5: add the Kconfig entry for the C2K board.

CONFIG_DEVICE_TREE was the only user of CONFIG_WANT_DEVICE_TREE but
it was removed in commit id 25431333813686654907ab987fb5de10c10a16db
(bootwrapper: Build multiple cuImages).
This removes CONFIG_WANT_DEVICE_TREE from Kconfig and the defconfigs.

The various embedded 6xx systems can easily coexist in one kernel
together with the other 6xx based systems, so there is no strict
reason to keep them separate.

The TSI108 code and the 32 bit powermac and chrp platforms
have dependency on PCI that is not easy or desirable to get rid
of.
The easiest fix is to always select CONFIG_PCI if one of those
platforms is enabled.

This patch creates platform_device entries for the Marvell mv64x60
MPSC (multi-protocol serial controller) ports, based on information
contained in the device tree.
This driver (like the other mv64x60 drivers) are unusual in that it
works on both the MIPS and PowerPC architectures. Because of that,
the drivers do not support the normal PowerPC of_platform_bus_type.
They support platform_bus_type instead.

When we started arch/powerpc we duplicated a number of config options from
arch/ppc for various platforms that are supported. Now that we actually
support a few platforms, remove all the ones that haven't been moved over.
Additionally, this cleanup moved the 82xx/PQ2 options over into
arch/powerpc/platforms/82xx/Kconfig where they belong. It also killed
GEN550 which doesn't exist in arch/powerpc.

This adds a new hardware information table for mpic. This enables
the mpic code to deal with mpic controllers with different register
layouts and hardware behaviours.
This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic
controllers, select CONFIG_MPIC_WEIRD and add its hardware information
in the mpic_infos[] array.
TSI108/109 PIC takes the first index of weird hardware information
table. :) The table can be extended. The Tsi108/109 PIC looks like
standard OpenPIC but, in fact, is different in register mapping and
behavior.
The patch does not affect the behavior of standard mpic. If
CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to
the current code.
[benh@kernel.crashing.org:
This patch is a slightly cleaned up version of Zang Roy's support for
the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new
version of the type macros and changes the way MPIC is selected in
Kconfig to better match what is done for other system devices.

Updated Kconfig & Makefiles in prep for adding support for the Freescale
MPC83xx family of processors to arch/powerpc. Moved around some config

This changes the parameters for i8259_init so that it takes two
parameters: a physical address for generating an interrupt
acknowledge cycle, and an interrupt number offset. i8259_init
now sets the irq_desc[] for its interrupts; all the callers
were doing this, and that code is gone now. This also defines
a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and
makes the platforms that need it select that symbol.

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files. It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.
For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes
to files in those directories and files outside arch/powerpc.
The boot directory is still not merged. That's going to be interesting.
