f0c0b3a9e6 Fix incorrect use of getenv() before relocation
A large number of boards incorrectly used getenv() in their board init
code running before relocation.  In some cases this caused U-Boot to
hang when certain environment variables grew too long.
Fix the code to use getenv_r().

b36df56115 ppc4xx: Move ppc4xx headers to powerpc include directory
This patch moves some ppc4xx related headers from the common include
directory (include/) to the powerpc specific one
(arch/powerpc/include/asm/). This way to common include directory is not
so cluttered with files.

This patch removes the duplicted implementations of the pci_master_init()

9a81c61249 ppc4xx: Remove duplicated is_pci_host() functions
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.

d1c3b27525 ppc4xx: Big cleanup of PPC4xx defines
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.

e321801bed ppc4xx: Remove redundant ft_board_setup() functions from some 4xx boards
This patch removes some ft_board_setup() functions from some 4xx boards.
This can be done since we now have a default weak implementation for this
in cpu/ppc4xx/fdt.c. Only board in need for a different/custom
implementation like canyonlands need their own version.

9973e3c614 Change initdram() return type to phys_size_t
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.

bbeff30cbd ppc4xx: Remove superfluous dram_init() call or replace it by initdram()
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.

5a5958b7de ppc4xx: Fix incorrect 33/66MHz PCI clock log-message on Sequoia & Yosemite
The BCSR status bit for the 66MHz PCI operation was correctly
addressed (MSB/LSB problem). Now the correct currently setup
PCI frequency is displayed upon bootup.

This patch also fixes this problem on Rainier & Yellowstone, since these
boards use the same souce code as Sequoia & Yosemite do.

3d9569b232 Changed PPC44x startup message (cpu info, speed...) to common style:
On PPC44x platforms, the startup message generated in "cpu.c" only
comprised the ppc type and revision but not additional informations
like speed etc. Those speed infos where printed in the board specific
code. This new implementation now prints all CPU infos in the common
cpu specific code. No board specific code is needed anymore and
therefore removed from all current 44x implementations.
