As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

This patch adds new macros, with frequently used combinations of the
4xx TLB access control and storage attibutes. Additionally the 4xx init.S
files are updated to make use of these new macros. Resulting in easier
to read TLB definitions.
Additionally some init.S files are updated to use the mmu header for the
TLB defines, instead of defining their own macros.

The appropriate include/asm-$ARCH directory should already by symlinked
to include/asm so using the whole "asm-$ARCH" path is unnecessary.
This change should also allow us to move the include/asm-$ARCH
directories into their appropriate lib/$ARCH/ directories.

Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk
This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.

This patch introduces a weak default function for post_hotkey_pressed(),
returning 0, for boards without hotkey support. The long-running tests
won't be started on those boards. This default function was implemented
in many board directories. By implementing this weak default we can
remove all those duplicate versions.
Boards with hotkey support, can override this weak default function
by defining one in their board specific code.

This patch removes the duplicted implementations of the pci_target_init()
function by introducing a weak default function for it. This weak default
has a different implementation for 440EP(x)/GR(x) PPC's. It can be
overridden by a board specific version (e.g. PMC440, korat).

This patch introduces a weak default function for is_pci_host(),
returning 1. This is the default behaviour, since most boards only
implement PCI host functionality. This weak default can be overridden
by a board specific version if needed.

All these linker scripts can be removed since the new common ppc4xx
linker script should be able to handle all of those boards.
Please test and report problems. Thanks.

The following changes allow U-Boot to fully relocate from flash to
RAM:
- Remove linker scripts' .fixup sections from the .text section
- Add -mrelocatable to PLATFORM_RELFLAGS for all boards
- Define CONFIG_RELOC_FIXUP_WORKS for all boards
Previously, U-Boot would partially relocate, but statically initialized
pointers needed to be manually relocated.

The latest PPC4xx register cleanup patch missed some SDRAM defines.
This patch now changes lower case UIC defines to upper case. Also
some names are changed to match the naming in the IBM/AMCC users
manuals (e.g. mem_mcopt1 -> SDRAM0_CFG).

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:
- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines
Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.
This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.
Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

Historically the 405 U-Boot port had a dram_init() call in early init
stage. This function was still called from start.S and most of the time
coded in assembler. This is not needed anymore (since a long time) and
boards should implement the common initdram() function in C instead.
This patch now removed the dram_init() call from start.S and removes the
empty implementations that are scattered through most of the 405 board
ports. Some older board ports really implement this dram_init() though.
These are:
csb272
csb472
ERIC
EXBITGEN
W7OLMC
W7OLMG
I changed those boards to call this assembler dram_init() function now
from their board specific initdram() instead. This *should* work, but please
test again on those platforms. And it is perhaps a good idea that those
boards use some common 405 SDRAM initialization code from cpu/ppc4xx at
some time. So further patches welcome here.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
