This patch fixes a numbers of issues regarding to that both 8xx and 82xx
began to use ppc_sys model:
	- Platform is now identified by default deviceless SOC, if no
BOARD_CHIP_NAME is specified in the bard-specific header. For the list
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and
mpc82xx_sys.c for 8xx and 82xx respectively.
	- Fixed a bug in identification by name - if the name was not found,
it returned -1 instead of default deviceless ppc_spec.
	- fixed devices amount in the 8xx platform system descriptions

Change the phys_mem_access_prot() function to take a pfn instead of an
address.  This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures.  We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.

Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn.  Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.

Here is an uptodated version of the MPC8xx PCMCIA driver for v2.6,
addressing comments by Jeff and Dominik:

- use IO accessors instead of direct device memory referencing
- avoid usage of non-standard "uint/uchar" data types
- kill struct typedef's

Will submit it for inclusion once v2.6.14 is out.

Testing on 8xx platforms is more than welcome! Works like a charm
on our custom hardware (CONFIG_PRxK).

Convert core 8xx drivers to use in_xxxbe/in_xxx macros instead of direct
memory references.

Other than making IO accesses explicit (which is a plus for readability), a
common set of macros provides a unified place for the volatile flag to
constraint compiler code reordering.

There are several unlucky places at the moment which lack the volatile
flag.

Depending on how GCC is built, GCC 4 may generate altivec instructions without
user explicitly requesting vector operations in the code.  Although this is a
performance booster for user applications, it is a problem for kernel.

This patch explicitly instruct GCC to NOT generate altivec instructions while
building the kernel.

Here are some test cases I ran.

(1) build gcc 4.0.1 with '--with-cpu=7450 --enable-altivec
    --enable-cxx-flags=-mcpu=7450', and use this gcc to build kernel WITHOUT
    this kernel patch.  Kernel fail to boot up on a 7450 board because of
    altivec instructions in kernel.

(2) build gcc 4.0.1 with "--with-cpu=7450 --enable-altivec
    --enable-cxx-flags=-mcpu=7450", and use this gcc to build kernel WITH this
    kernel patch.  Kernel boot up on a 7450 board without any problem.

(3) build gcc 4.0.1 with "--with-cpu=750 --enable-cxx-flags=-mcpu=750",
    and use this gcc to build kernel with or without this kernel patch.
    Kernel boot up on a 7450 board without any problem.

This patch should also work with GCC 3 or even earlier GCC 2.95.3.

The merged version follows the ppc64 version pretty closely mostly,
and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version.
The main difference for ppc64 is that the 'p' command to call
show_state (which was always pretty dodgy) has been replaced by
the ppc32 'p' command, which calls a given procedure (so in fact
the old 'p' command behaviour can be achieved with 'p $show_state').

This patch moves the XICS interrupt controller code into the

case to remove pSeries specific assumptions.
