This patch adds support for dynamic configuration of PCIe ports for the
AMCC PPC4xx boards equipped with PCIe interfaces. These are the PPC440SPe
boards Yucca & Katmai and the 405EX board Kilauea.
This dynamic configuration is done via the "pcie_mode" environement
variable. This variable can be set to "EP" or "RP" for endpoint or
rootpoint mode. Multiple values can be joined via the ":" delimiter.
Here an example:
pcie_mode=RP:EP:EP
This way, PCIe port 0 will be configured as rootpoint, PCIe port 1 and 2
as endpoint.
Per default Yucca will be configured as:
pcie_mode=RP:EP:EP
Per default Katmai will be configured as:
pcie_mode=RP:RP:REP
Per default Kilauea will be configured as:
pcie_mode=RP:RP

This patch enables the fdt support on the AMCC Kilauea eval board.
Additionally now EBC ranges fdt fixup is included to support NOR
FLASH mapping via the Linux physmap_of driver.
This Kilauea port now support booting arch/ppc and arch/powerpc
Linux kernels. The default environment "net_nfs" is for arch/ppc
and "net_nfs_fdt" is for arch/powerpc. In the long run, arch/ppc
support will be removed.

128MB seems to be the smallest possible value for the memory size
for on PCIe port. With this change now the BAR's of the PCIe cards
are accessible under U-Boot.
One big note: This only works for PCIe port 0 & 1. For port 2 this
currently doesn't work, since the base address is now 0xc0000000
(0xb0000000 + 2 * 0x08000000), and this is already occupied by
CFG_PCIE0_CFGBASE. But solving this issue for port 2 would mean
to change the base addresses completely and this change would have
too much impact right now.
This patch adds debug output to the 4xx pcie driver too.

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

Found a bug in the way the DHCP Request packet is built, where the IP address
that is offered by the server is bound to prematurely. This patch is a fix of
that bug where the IP address offered by the DHCP server is not used until
after the DHCP ACK from the server is received.

With this patch PSC3 is configured as UART. This is done, because if
the pins of PSC3 are not configured at all (-> all pins are GPI),
due to crosstalk, spurious characters may be send over the RX232_2_TXD
signal line.

Some commands for the STK52xx base board try to access the SM501 grafic
controller. But the TQM5200S has no grafic controller (only the TQM5200
and the TQM5200B have). This patch deactivates the commands accessing
the SM501 for the TQM5200S.

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.

New board has faster oscillator and a different Flash chip. This affects:
- CFG_MPC5XXX_CLKIN
- SDRAM timings
- Flash CS configuration (timings)
- Flash sector size, and thus MTD partition layout
- malloc() arena size (due to bigger Flash sectors)
- smaller memory test range (due to bigger malloc() arena)
This patch also enables more extensive memory testing via "mtest".
