This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files
and to the Sequoia TLB init code. Now the cache can be enabled on 44x
boards by defining CONFIG_4xx_DCACHE in the board config file. This
option will disappear, when more boards use is successfully and no
more known problems exist.
This is tested successfully on Sequoia and Katmai. The only problem that
needs to be fixed is, that USB is not working on Sequoia right now, since
it will need some cache handling code too, similar to the 4xx EMAC driver.

The Haleakala is nearly identical with the Kilauea eval board. The only
difference is that the 405EXr only supports one EMAC and one PCIe
interface. This patch adds support for the Haleakala board by using
the identical image for Kilauea and Haleakala. The distinction is done
by comparing the PVR.

This patch adds endpoint support for the AMCC Kilauea eval board. It can
be tested by connecting a reworked PCIe cable (only 1x lane singles
connected) to another root-complex.
In this test setup, a 64MB inbound window is configured at BAR0 which maps
to 0 on the PLB side. So accessing this BAR0 from the root-complex will
access the first 64MB of the SDRAM on the PPC side.

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

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.

(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.

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

Now we load $gp with _GLOBAL_OFFSET_TABLE_, but this is incorrect use.
As a general principle, we should use _gp for $gp.
Thanks to linker script's help we fortunately have _gp which equals to
_GLOBAL_OFFSET_TABLE_. But once _gp gets out of alignment, we will not
be able to access to GOT entires, global variables and procedure entry
points. The right thing to do is to use _gp.
This patch also introduce a new symbol `.gpword _GLOBAL_OFFSET_TABLE_'
which holds the offset from _gp. When updating GOT entries, we use this
offset and _gp to calculate the final _GLOBAL_OFFSET_TABLE_.

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.
