- 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.
Patch by Stefan Roese, 28 Jul 2006
- 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)
The PS/2 keyobard driver for the TQM85xx modules only supports the
internal DUART of the MPC85xx CPU. Since the MPC8560 doesn't
include a DUART, the TQM8560 modules can't be used with the PS/2
keyboard controller on the STK85xx board.
The PS/2 keyboard driver should work with the modules TQM8540,
TQM8541 and TQM8555, but it only has been tested on a TQM8540, yet.
Make sure the PS/2 controller on the STK85xx is programmed. Jumper
settings: X66 1-2, 9-10; X61 2-3

During an automatic update via USB stick, U-Boot searches for
images with the name "firmware.img" and "kernel.img". This names
are now changed to "firmw_01.img" and "kernl_01.img". This is done,
to prevent updates of new boards (with the new macronics "c" step
flashes) with old, incompatible firmware or kernel versions.
Patch by Martin Krause, 21 Jun 2006
- increase CFG_FLASH_ERASE_TOUT from 2 to 15 seconds
- use CFG_FLASH_WRITE_TOUT for programming instead of CFG_FLASH_ERASE_TOUT
- remove "Unlock Bypass" mode, because macronix flashes do not support
this mode officially
- fix flash reset command from 0x00FF to 0x00F0. 0x00FF is only specified
for Intel compatible flashes, not for AMD compatible.

The TB5200 ("Tinybox") is a small baseboard for the TQM5200 module
integrated in a little aluminium case.
Patch by Martin Krause, 8 Jun 2006
Some code cleanup
Notes:
- Board-dependend code for RPXLITE and RPXCLASSIC-based boards
placed to the drivers/rpx_pmcia.c file to avoid duplication.
Same for TQM8xx-based boards (drivers/tqm8xx_pmcia.c).
- drivers/i82365.c has been split into two parts located at
board/atc/ti113x.c and board/cpc45/pd67290.c (ATC and CPC45 are
the only boards using CONFIG_82365).
- Changes were tested for clean build and *very* *few* boards.
Patch by Martin Krause, 8 Jun 2006
This patch supports two serial consoles on boards with
a MPC5xxx CPU. The console can be switched at runtime
by setting stdin, stdout and stderr to the desired serial
interface (serial0 or serial1). The PSCs to be used as
console port are definded by CONFIG_PSC_CONSOLE
and CONFIG_PSC_CONSOLE2.
See README.serial_multi for details.
If the bus is blocked because of a previously interrupted
transfer, up to eleven clocks are generated on the I2CSCL
line to complete the transfer and to free the bus.
With this fix pin I2CSCL (PG6) is really configured as GPIO
so the clock pulses are really generated.

Patch by Martin Krause, 07 Nov 2005
Tested on a STK85XX baseboard. Make sure the PS/2 controller
has been programmed. Jumper Settings: X66 1-2, 9-10; X61 2-3
Patch by Martin Krause, 08 Nov 2005
In tsc2000_read_channel() the delay after setting the multiplexer
to a temperature channel is increased from 1,5 ms to 10 ms. This
is to allow the multiplexer inputs to stabilize after huge steps
of the input signal level.
Make the automatic CS configuration the default.
The dedicated configurations CONFIG_TQM5200_AA, CONFIG_TQM5200_AB
and CONFIG_TQM5200_AC are removed.
"TQM5200_config" is now the default for STK52XX.200 base boards.
On a STK52XX.100 base board "TQM5200_STK100_config" must be used.
Patch by Martin Krause, 07 Nov 2005
The environment variable "ver" is now set before
do_auto_update() is called, so that "ver" can be used
in USB update scripts.
Patch by Martin Krause, 27 Oct 2005
-When booting from an epcs controller, the epcs bootrom may leave the
slave select in an asserted state causing soft reset hang. This
patch ensures slave select is negated at reset.

-Fix asm/io.h macros
-Eliminate use of CACHE_BYPASS in cpu code
-Eliminate assembler warnings
