- Add support for PPC440EPx & PPC440GRx
- Add support for PPC440EP(x)/GR(x) NAND controller
in cpu/ppc4xx directory
- Add NAND boot functionality for Sequoia board,
please see doc/README.nand-boot-ppc440 for details
- This Sequoia NAND image doesn't support environment
in NAND for now. This will be added in a short while.

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
AMCC suggested to set the PMU bit to 0 for best performace on
the PPC440 DDR controller.
Please see doc/README.440-DDR-performance for details.

The TB5200 ("Tinybox") is a small baseboard for the TQM5200 module
integrated in a little aluminium case.

Some code cleanup
405 SDRAM: - The SDRAM parameters can now be defined in the board
config file and the 405 SDRAM controller values will
be calculated upon bootup (see PPChameleonEVB).
When those settings are not defined in the board
config file, the register setup will be as it is now,
so this implementation should not break any current
design using this code.
Thanks to Andrea Marson from DAVE for this patch.
440 DDR: - Added function sdram_tr1_set to auto calculate the
TR1 value for the DDR.
- Added ECC support (see p3p440).

On PPC44x platforms, the startup message generated in "cpu.c" only
comprised the ppc type and revision but not additional informations
like speed etc. Those speed infos where printed in the board specific
code. This new implementation now prints all CPU infos in the common
cpu specific code. No board specific code is needed anymore and
therefore removed from all current 44x implementations.

- Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c
- CFG_FLASH_QUIET_TEST added to use the common CFI driver
for bank autodetection
