This rearranges a bit of code, and adds support for
36-bit physical addressing for configs that use a
hashed page table. The 36b physical support is not
enabled by default on any config - it must be
explicitly enabled via the config system.
This patch *only* expands the page table code to accomodate
large physical addresses on 32-bit systems and enables the
PHYS_64BIT config option for 86xx. It does *not*
allow you to boot a board with more than about 3.5GB of
RAM - for that, SWIOTLB support is also required (and
coming soon).

There's no good reason why a resource_size_t shouldn't just be a
physical address, so simply redefine it in terms of phys_addr_t.

Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression. This
patch makes this easier by changing:
bool "PCI support" if <long expression>
to
bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.
Platforms with unconditional PCI support continue to
just select PCI in their config nodes.

At present, if we have a kernel with a 64kB page size, and some
process maps something that has to be mapped with 4kB pages (such as a
cache-inhibited mapping on POWER5+, or the eHCA infiniband queue-pair
pages), we change the process to use 4kB pages everywhere. This hurts
the performance of HPC programs that access eHCA from userspace.
With this patch, the kernel will only demote the slice(s) containing
the eHCA or cache-inhibited mappings, leaving the remaining slices
able to use 64kB hardware pages.
This also changes the slice_get_unmapped_area code so that it is
willing to place a 64k-page mapping into (or across) a 4k-page slice
if there is no better alternative, i.e. if the program specified
MAP_FIXED or if there is not sufficient space available in slices that
are either empty or already have 64k-page mappings in them.

The new e500mc core from Freescale is based on the e500v2 but with the
following changes:
* Supports only the Enhanced Debug Architecture (DSRR0/1, etc)
* Floating Point
* No SPE
* Supports lwsync
* Doorbell Exceptions
* Hypervisor
* Cache line size is now 64-bytes (e500v1/v2 have a 32-byte cache line)

This patch creates a common system reset routine for all 40x and 44x
systems. Previously only a 44x routine existed. But since this system
reset via the debug control register is common for 40x and 44x let's
share this code for all those platforms in ppc4xx_soc.c.
This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms.
Tested on Kilauea (405EX) and Canyonlands (440EX).

Not all e300 cores support the performance monitors, and the ones
that don't will be confused by the mf/mtpmr instructions. This
allows the support to be optional, so the 8349 can turn it off
while the 8379 can turn it on. Sadly, those aren't config options,
so it will be left to the defconfigs and the users to make that
determination.

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.

Some of the more recent e300 cores have the same performance monitor
implementation as the e500. e300 isn't book-e, so the name isn't
really appropriate. In preparation for e300 support, rename a bunch
of fsl_booke things to say fsl_emb (Freescale Embedded Performance Monitors).

* Removed Kconfig option 'PPC_MPC836x' since its not used
* Renamed Kconfig option 'MPC834x' to 'PPC_MPC834x' to match others
* Added a multiplatform 83xx defconfig (mpc83xx_defconfig).

Currently there's no way to enable early boot console on PowerPC 44x
not specifying uart's physical address in kernel config, which is used
for very early debug messages. This patch splits very early debug output
(which needs uart physical address in kernel config) and early boot console
(which searches for uarts in the device tree using find_legacy_serial_ports).
We enable early boot console for all 44x processors, while (dangerous)
early debug is user-selectable.

The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.
Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.

A lot of the options in arch/powerpc/Kconfig deal with the CPU menu,
and my next patches add more to them. Moving them to a new
arch/powerpc/platforms/Kconfig.cputype file makes it easier to
follow.
There are no functional changes in here.
