Previous versions used full wait states for the chip select #1 which
is connected to the Xilinix SystemACE controller on the AMCC Katmai
evaluation board. This leads to really slow access and therefore low
performance. This patch now sets up the chip select a lot faster
resulting in much better read/write performance of the Linux driver.

Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.
As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.

The AMCC Luan now uses the common 440SP(e) DDR SPD code for DDR
inititializition. This includes DDR auto calibration and support
for different DIMM modules, instead of the fixed setup used in
the earlier version.
This patch also enables the cache in FLASH for the startup
phase of U-Boot (while running from FLASH). After relocating to
SDRAM the cache is disabled again. This will speed up the boot
process, especially the SDRAM setup, since there are some loops
for memory testing (auto calibration).

The patch solves the alignment problem of the local bus access windows to
render accessible the memory bank and PHY registers of UPC 1 (starting at
0xf801 0000). What we actually did was to adjust the sizes of the bus
access windows so that the base address alignment requirement would be met.

I've redone the SBC8349 support to match git-current, which
incorporates all the MPC834x updates from Freescale since the 1.1.6
release, including the DDR changes.
I've kept all the SBC8349 files as parallel as possible to the
MPC8349EMDS ones for ease of maintenance and to allow for easy
inspection of what was changed to support this board. Hence the SBC8349
U-Boot has FDT support and everything else that the MPC8349EMDS has.
Fortunately the Freescale updates added support for boards using CS0,
but I had to change spd_sdram.c to allow for board specific settings for
the sdram_clk_cntl (it is/was hard coded to zero, and that remains the
default if the board doesn't specify a value.)
Hopefully this should be mergeable as-is and require no whitespace
cleanups or similar, but if something doesn't measure up then let me
know and I'll fix it.
Thanks,
Paul.
This patch updates the recently added Katmai board support. The biggest
change is the support of ECC DIMM modules in the 440SP(e) SPD DDR2
driver.
Please note, that still some problems are left with some memory
configurations. See the driver for more details.

The original search_one_table() function code can only processes the search
for the exception occurring in FLASH/ROM, because the exception and fixup
table usually locate in FLASH. If the exception address is also in
FLASH, it will be OK.
If the exception occurs in RAM, after the u-boot relocation, a
relocation offset should be added.
