These files were introduced with the IBM 405GP but are currently used on all
4xx PPC platforms. So the name doesn't match the content anymore. This patch
renames the files to 4xx_pci.c/h.

(3) This patch introduces macros like SDRN_PESDR_DLPSET(port) to access
the SDR registers of the PCIe ports. This makes the overall design
clearer, since it removed a lot of switch statements which are not
needed anymore.
Also, the functions ppc4xx_init_pcie_rootport() and
ppc4xx_init_pcie_entport() are merged into a single function
ppc4xx_init_pcie_port(), since most of the code was duplicated.
This makes maintainance and porting to other 4xx platforms
easier.

This patch is the first patch of a series to make the 440SPe PCIe code
usable on different 4xx PPC platforms. In preperation for the new 405EX
which is also equipped with PCIe interfaces.
(2) This patch renames the functions from 440spe_ to 4xx_ with a
little additional cleanup

The pxa255_idp being an old unmaintained board showed several issues:
1. CONFIG_INIT_CRITICAL was still defined.
2. Neither CONFIG_MAC_PARTITION nor CONFIG_DOS_PARTITION was defined.
3. Symbol flash_addr was undeclared.
4. The boards lowlevel_init function was still called memsetup.
5. The TEXT_BASE was still 0xa3000000 rather than 0xa3080000.
6. Using -march=armv5 instead of -march=armv5te resulted in lots of
'target CPU does not support interworking' warnings on recent compilers.
7. The PXA's serial driver redefined FFUART, BTUART and STUART used as
indexes rather than the register definitions from the pxa-regs header
file. Renamed them to FFUART_INDEX, BTUART_INDEX and STUART_INDEX to
avoid any ambiguities.
8. There were several redefinition warnings concerning ICMR, OSMR3,
OSCR, OWER, OIER, RCSR and CCCR in the PXA's assembly start file.
9. The board configuration file was rather outdated.
10. The part header file defined the vendor, product and revision arrays
as unsigned chars instead of just chars in the block_dev_desc_t
structure.

As a direct correlation exists between DDR DIMM slots
and SPD EEPROM addresses used to configure them, use
the individually defined SPD_EEPROM_ADDRESS* values to
determine if a DDR DIMM slot should have its SPD
configuration read or not.
Effectively, this now allows for 1 or 2 DIMM slots
per memory controller.

Some USB keys need to be switched off before loading the kernel
otherwise they can remain in an undefined status which prevents them
to be correctly recognized by the kernel.

Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the
first device on the first bus. We now allow to configure up to 16 buses;
also, scanning for devices behind the PCIe-PCIe bridge is supported, so
peripheral devices farther in hierarchy can be identified.

Convert using fixup mechanism to suppressing MCK for the duration of config
read/write transaction: while fixups work fine with the case of a precise
exception, we identified a major drawback with this approach when there's
an imprecise case. In this scenario there is the following race condition:
the fixup is (by design) set to catch the instruction following the one
actually causing the exception; if an interrupt (e.g. decrementer) happens
between those two instructions, the ISR code is executed before the fixup
handler the machine check is no longer protected by the fixup handler as it
appears as within the ISR code. In consequence the fixup approach is being
phased out and replaced with explicit suppressing of MCK during a PCIe
config read/write cycle.

When frame larger than local RX buffer is received, it is split and handled
by two buffer descriptors. Prior to this patch the FEC driver discarded
contents of a buffer descriptor without the 'LAST' bit set, so the first
part of the frame was lost in case of larger frames. This fix allows to
safely combine the two pieces into the whole frame.

Tested on: lite5200b
Note: the fixup functions have not been moved to a common place. This
patch is targeted for immediate merging as in solves a build issue, but
the final name/location of the fixups is still subject to debate. I
propose to merge this now, and move the fixups in the next merge window
to be usable by all targets.
