Fix a bug in the auto calibration routine. This driver now runs
more reliable with the tested modules. It's also tested with
167MHz PLB frequency (667MHz DDR2 frequency) on the Katmai.

This patch adds support for the new AMCC 405EZ PPC. It is in

Please note that this Acadia/405EZ support is still in a beta stage.
Still lot's of cleanup needed but we need a preliminary release now.

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).

This patch fixes a problem that occurs when 2 DIMM's are
used. This problem was first spotted and fixed by Gerald Jackson
<gerald.jackson@reaonixsecurity.com> but this patch fixes the
problem in a little more clever way.
This patch also adds the nice functionality to dynamically
create the TLB entries for the SDRAM (tlb.c). So we should
never run into such problems with wrong (too short) TLB
initialization again on these platforms.
As this feature is new to the "old" 44x SPD DDR driver, it
has to be enabled via the CONFIG_PROG_SDRAM_TLB define.

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.

For better format and style, I streamlined the 83xx head files,
including immap_83xx.h and mpc83xx.h. In the old head files, 1)
duplicated macro definition appear in the both files; 2) the structure
of QE immr is duplicated in the immap_83xx.h and immap_qe.h; 3) The
macro definition put inside the each structure. So, I cleaned up the
structure of QE immr from immap_83xx.h, deleted the duplicated stuff and
moved the macro definition to mpc83xx.h, Just like MPC8260.

This patch updates the recently added Katmai board support. The biggest

This patch adds support for the DDR2 controller used on the
440SP and 440SPe. It is tested on the Katmai (440SPe) eval

- Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM)

It also merges the 405 and 440 i2c header files into one common

some problems with the first access on the 440SPe Katmai board.
