- Map in a additional chip selects CS4 and CS5.
- Modify the port configration, configure six UARTs and no PCI,
ATA and USB.
- Add custom flash driver to handle specific byte swapping
- 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.
Patch by Stefan Roese, 07 Sep 2006
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.
Improved the memory DIMM detection for the Yucca 440SPe board for
the case where a memory DIMM is falsely detected as present.
This issue is seen on some AMCC Yucca 440SPe validation boards if
only one 512MB memory DIMM is installed, i.e. DIMM slot 0 is
populated and DIMM slot 1 is empty. In this case, U-Boot does
not correctly detect that there is only one DIMM memory module
installed and will falsely detect two DIMM memory modules are
present and therefore U-Boot will not calculate the correct amount
of total memory and u-boot will not booting up.

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.

- make highboot configurations use environment at high end, too,
to avoid flash fragmentation
- always use redundand environment
- don't enable video code for modules without graphics controller
- provide useful (though different) mtdparts settings
- get rid of CONFIG_CS_AUTOCONF which was always set anyway
* Extend mkconfig tool to print more useful target name
Hint: the CPLD on the TQM5200 must be programmed with a software
version supporting the high boot option! The new TQM5200S is
already supporting this option. On the TQM5200 this option will be
supported in configurations with MPC5200 rev B processors.
To actually "high boot", set jumper X30 on the STK52xx.
Patch by Martin Krause, 12 Jul 2006
- Support for TQM5200S (short version without graphic controller)
- Support for modules with 'N' type S29GL128N Spansion flashes
(requires changes to flash layout)
- Support for MPC5200B cpu (mostly support for second SDRAM bank)
