This patch series unifies the AMCC eval board ports by introducing
a common include header for all AMCC eval boards:
include/configs/amcc-common.h
This header now includes all common configuration options/defines which
are removed from the board specific headers.
The reason for this is ease of maintenance and unified look and feel
of all AMCC boards.

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 patch changes the kilauea and kilauea_nand (for NAND booting)
board port to not use a board specific DDR2 init routine anymore. Now
the common code from cpu/ppc4xx is used.
Thanks to Grant Erickson for all his basic work on this 405EX early
bootup.

This patch (Part 2 of 2):
* Rolls up a suite of changes to enable correct primordial stack and
global data handling when the data cache is used for such a purpose
for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).
* Related to the first, unifies DDR2 SDRAM and ECC initialization by
eliminating redundant ECC initialization implementations and moving
redundant SDRAM initialization out of board code into shared 4xx
code.
* Enables MCSR visibility on the 405EX(r).
* Enables the use of the data cache for initial RAM on
both AMCC's Kilauea and Makalu and removes a redundant
CFG_POST_MEMORY flag from each board's CONFIG_POST value.
- Removed, per Stefan Roese's request, defunct memory.c file for
Makalu and rolled sdram_init from it into makalu.c.
With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

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.

When SATA is selected (via jumper J6) we need to disable the first PCIe
node in the device tree, so that Linux doesn't initialize it. Otherwise
the Linux SATA driver will fail to detect the devices.
The same goes the other way around too. So if PCIe is selected we need
to disable the SATA node in the device tree.
This is because PCIe port 0 and SATA on 460EX share the same pins
(multiplexed) and we have to configure in U-Boot which peripheral is
enabled.

Several board/<...>/config.mk files include dynamically built (by
the Makefile) config files but used the wrong file name of
$(TOPDIR)/board/$(BOARDDIR)/config.tmp
instead if the correct
$(OBJTREE)/board/$(BOARDDIR)/config.tmp
The bug is nasty because the build result is correct for the (normal)
in-tree builds, and because 'sinclude' is used no errors get raised
even for out-of-tree build tests. But out-of-tree builds use an
incomplete and thus usually incorrect configuration...

When applying the AT91CAP9 patches upstream, something transformed
the '@' character into the ' <at> ' sequence.
The patch below restores the original form in all the places where
it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
were copied from AT91CAP9, and a couple of other files where the
' <at> ' sequence was present).

When doing the AT91CAP9/AT91SAM9 port, a number of header files were
copied from the Linux kernel sources. This patch explicitly specifies
this origin for all the copied headers, and for those missing copyright
information, adds it.
Additionaly, the header file 'at91sam926x_mc.h' has been superceeded
in the latest kernel sources by 'at91sam9_smc.h'.
The copyright information has been confirmed by the AT91 Linux kernel
maintainer, Andrew Victor <avictor.za@gmail.com>.

This patch adds fdt (flattened device tree) support to the AMCC
Acadia eval board. This increases the image size and it doesn't
fit anymore into 256kByte. Since we didn't want to remove features
from the configuration, we decided to increase the U-Boot image size
(add one flash sector).
Also changed the default environment definition to make it
independent of such changes.

Since the current dflush() implementation is know to have some problems
(as seem on lwmon5 ECC init) this patch removes it completely and replaces
it by using clean_dcache_range().
Tested on Katmai with ECC DIMM.

As it seems the "old" ECC initialization routine by using dflush() didn't
write all lines in the dcache back to memory on lwmon5. This could lead
to ECC error upon Linux booting. This patch changes the program_ecc()
routine to now use clean_dcache_range() instead of dflush().
clean_dcache_range() uses dcbst which is exactly what we want in this
case.
Since dflush() is known is cause problems, this routine will be
removed completely and replaced by clean_dcache_range() with an
additional patch.
