Bamboo has a file sdram.c which needs special treatment when building in
separate directory. It has to be linked to build directory otherwise it is
not seen.

- 'pciconfighost' is set by default in order to be able to scan bridges
behind the primary host/PCIe
- 'pciscandelay' env variable is recognized to allow for user-controlled
delay before the PCIe bus enumeration; some peripheral devices require a
significant delay before they can be scanned (e.g. LSI8408E); without the
delay they are not detected

- correct configuration space mapping
- correct bus numbering
- better access to config space
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.

Stop using inline string functions on MIPS as other ARCHs do so,
since the optimized inline asm versions are not small.
This change is triggered by a following MIPS build error:
common/libcommon.a(exports.o)(.text+0xdc): In function `jumptable_init':
common/exports.c:32: undefined reference to `strcmp'
make: *** [u-boot] Error 1

This patches contains several bugfixes and cleanups in the latest upstream:
- Don't include linux/config.h
- Remove buggy inline version of memscan.
- Merge with Linux 2.6.11-rc3.
- Fix undefined reference to strcpy in binfmt_misc caused by gcc 3.4.
- Goodbye mips64. 31704 lines of code bite the dust.
- Replace extern inline with static inline.
- Fix return value of strncpy.
- Remove a bunch more "$1" clobbers.

Fix incorrect blob address calculation in do_bootm_linux() that prevents
booting the kernel from a multi-file image (kernel + initrd + blob).
Also, make minor updates to the U-Boot's output and to the coding style.

Boards with CONFIG_OF_LIBFDT enabled are not able to boot old-style
kernels using the board info structure (instead of passing a device tree)
This change allows the old style booting to be used if the fdt argument
was not passed to 'bootm'.

Affects boards: icecube (lite5200), jupiter, motionpro, tqm5200
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.

The RTC on the M1575 ULI chipset requires a dummy read before
we are able to talk to the RTC. We accomplish this by adding a
second memory region to the PHB the ULI is on and read from it.
The second region is added to maintain compatiabilty with Linux's
view of the PCI memory map.

The 440EPx has a problem when the PCI_CACHE_LINE_SIZE register is
set to non-zero, because it doesn't support MRM (memory-read-
multiple) correctly. We now added the possibility to configure
this register in the board config file, so that the default value
of 8 can be overridden.
Here the details of this patch:
o drivers_pci_auto.c: introduce CFG_PCI_CACHE_LINE_SIZE to allow
board-specific settings. As an example the sequoia board requires 0.
Idea from Stefan Roese <sr@denx.de>.
o board/amcc/sequoia/init.S: add a TLB mapping at 0xE8000000 for the
PCI IO-space. Obtained from Stefan Roese <sr@denx.de>.
o include/configs/sequoia.h: turn CONFIG_PCI_PNP back on and set
CFG_PCI_CACHE_LINE_SIZE to 0.

The old code had a loop limit overflow bug which caused a semi-
infinite loop for small packets, because in "i<len-8", "i" was signed,
but "len" was unsigned, and "len-8" became a huge number for small
values of "len".
This is a workaround which replaces broken commit 8f1bc284.
