This patch removes the duplicted implementations of the pci_pre_init()
function by introducing a weak default function for it. This weak default
has a different implementation for some PPC variants. It can be
overridden by a board specific version.

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.

The latest PPC4xx register cleanup patch missed the UIC defines.
This patch now changes lower case UIC defines to upper case.
Signed-off-by: Stefan Roese <sr@denx.de>
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.

The XPedite1000 is an X-ES product thus it can be put in board/xes along
with other X-ES boards. Along with the move, the board was renamed to
XPedite1000 from XPedite1K to fit X-ES's standard naming convention.
Maintainership was also transfered to Peter Tyser.

The XPedite1000 can be built with 4 total flashes:

By default, the XPedite1000 comes installed with xMon, a proprietary
bootloader. xMon stores its MAC address in an onboard EEPROM. Rather
than requiring a non-standard location in the EEPROM to be reserved for
MAC addresses, store the MAC addresses in U-Boot's standard environment.
A U-Boot application or OS application can be used to migrate xMon MAC
addresses to U-Boot's environment if necessary.

Using the CFI flash driver will allow write access to the 16MB Intel
StrataFlash present on the XPedite1000. The 512KB socketed (non
CFI-compliant flash) will no longer be writable.
The mapping of the 16MB Strata flash was moved to 0xff000000 and the
512KB AMD socketed flash was moved to 0xfe000000.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
Rather than have the common ppc code have board-specific hooks, move the
board_get_enetaddr() function into the board-specific init functions.

This patch reworks the 440GX interrupt handling so that the common 4xx
code can be used. The 440GX is an exception to all other 4xx variants
by having the cascading interrupt vectors not on UIC0 but on a special
UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references
the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt
handling is simpler without any 440GX special cases.
Also some additional cleanup to cpu/ppc4xx/interrupt.c is done.

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.

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.
