Fix empty i2c reads/writes, i2c_write(0x50, 0x00, 0, NULL, 0)
which is used to se if an slave will ACK after receiving its address.
Correct i2c probing to use this method as the old method could upset
a slave as it wrote a data byte to it.
Add a small delay in i2c_init() to let the controller
shutdown any ongoing I2C activity.

Add support for the MPC8349E-mITX-GP, a stripped-down version of the
MPC8349E-mITX. Bonus features include support for low-boot (BMS bit in
HRCW is 0) for the ITX and a README for the ITX and the ITX-GP.

There is no SDRAM on any of the 8349 ITX variants, so function sdram_init()
never does anything. This patch deletes it.

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.

don't hang if watchdog configured on 8360, 832x
The watchdog programming model is the same across all 83xx devices;
make the code reflect that.

protect memcpy to bad address if a local-mac-address is missing from dt

The problem is not gcc4 but the code itself. The BD_STATUS() macro can't
be used for busy-waiting since it strips the 'volatile' property from
the bd variable. gcc3 was working by pure luck.
This is a follow on patch to "Fix the UEC driver bug of QE"

The code that is ifdef'd with CONFIG_MPC8349 is actually applicable to all
MPC834X class processors. Change the protections from CONFIG_MPC8349 to
CONFIG_MPC834X so they are more generic.

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.
CHANGELOG
*streamline the 83xx immr head file

The patch prevents the GCC tool chain from striping useful code for
optimization. It will make UEC ethernet driver workable, Otherwise the
UEC will fail in tx when you are using gcc4.x. but the driver can work
when using gcc3.4.3.

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.

Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.

This patch enables the "new" get_dev() function for block devices
introduced by Grant Likely to be used on systems that still suffer
from the relocation problems (manual relocation neede because of
problems with linker script).
Hopefully we can resolve this relocation issue soon for all platform
so we don't need this additional code anymore.

This patch adds support for the DDR2 controller used on the
440SP and 440SPe. It is tested on the Katmai (440SPe) eval
board and works fine with the following DIMM modules:
- Corsair CM2X512-5400C4 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM)
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.

Since the existing 4xx SPD SDRAM initialization routines for the
405 SDRAM controller and the 440 DDR controller don't have much in
common this patch splits both drivers into different files.
This is in preparation for the 440 DDR2 controller support (440SP/e).

This patch adds support for multiple I2C busses on the PPC4xx
platforms. Define CONFIG_I2C_MULTI_BUS in the board config file
to make use of this feature.
It also merges the 405 and 440 i2c header files into one common
file 4xx_i2c.h.
Also the 4xx i2c reset procedure is reworked since I experienced
some problems with the first access on the 440SPe Katmai board.
