Changes since U-Boot 1.1.4:
======================================================================
* Prevent USB commands from working when USB is stopped.
* Add rudimentary handling of alternate settings of USB interfaces.
This is in order to fix issues with some USB sticks timing out
during initialization. Some code readability improvements.
* PPC440 DDR setup: Set SDRAM0_CFG0[PMU]=0 for best performance
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
* AMCC bamboo (440EP) U-Boot image reduced to 384kbyte
Please see doc/README.bamboo for details.
Patch by Stefan Roese, 27 Jul 2006
* Fix CONFIG_CMDLINE_EDITING implementation
Patch by Stefan Roese, 27 Jul 2006
* Fix preboot message on TQM5200 after switching to hush parser.

and support for configurable options high_boot and/or SDRAM.
* Add support for 256 MB SDRAM on CPU87
Patch by Josef Wagner, 25 Nov 2005
* Add configuration for cam5200 board (based on TQM5200S).
* More code cleanup
* Disabled kvme080 board in MAKEALL because of build problems.
* Code cleanup

Patch by Ladislav Michl, 03 Nov 2005
* Make code better readable.
Patch by Ladislav Michl, 14 Sep 2005
* Enable initrd ATAG for xm250 board.
Patch by Josef Wagner, 05 Sep 2005

Patch by David Updegraff, 19 Aug 2005
* Add support for KVME080 board
Patch by Sangmoon Kim, 18 Aug 2005
* Fix MIPS LE build problem
Patch by Matej Kupljen, 10 Aug 2005
* Check argument count in "mii" command.
Problem pointed out by Andrew Dyer, 13 Jun 2005
* Cleanup TQM5200 board configurations:
- 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
* Add support for high-boot on TQM5200 and TQM5200S boards.
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
* Add support for new TQM5200 revisions
- 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)
Patch by Martin Krause, 07 Jul 2006
* Fix support for PS/2 keyboard on TQM85xx boards
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
Patch by Martin Krause, 21 Jun 2006
* Adjust RTC century handling on STK52xx board to match Linux driver.
Patch by Martin Krause, 12 Jun 2006
* Adjust filenames for USB update images on TRAB board.
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
* Bugfix in VFD routine on TRAB board.
Make sure upper lext pixel can be set to blue, too
(so far only red was possible).
Patch by Martin Krause, 15 Feb 2006
* Enable buffered flash writes for TB5200 board.
* Fix some bugs in TRAB board flash driver.
- 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.
Patch by Martin Krause, 15 Feb 2006
* Add additional error messages to flash driver on TRAB board
(for erase errors and timeout errors)
Patch by Martin Krause, 14 Feb 2006
* Add support for TB5200 board
The TB5200 ("Tinybox") is a small baseboard for the TQM5200 module
integrated in a little aluminium case.
Patch by Martin Krause, 8 Jun 2006
* Enable buffered flash writes for TQM5200 board.
* Fix problems with SanDisk Corporation Cruzer Micro USB memory stick.
* Add support for TQM885D board.
Patch by Martin Krause, 20 Mar 2006
* Fix FEC initialisation: All MII configuration is done via FEC1
registers, but MII_SPEED was configured according to FEC used. So
if only FEC2 was used, this caused the real MII_SPEED register in
FEC1 to stay uninitalised, leqading to "mii_send STUCK!" messages.
Fix: always configure MII_SPEED on FEC1 only.
Patch by Markus Klotzbuecher, 12 Jul 2006
* Add support for SPC1920 board.
Patch by Markus Klotzbuecher, 12 Jul 2006
* MCC200 board: support console on any one of the Quad UART ports.
* Fix error in flash protection calculation on MCC200 board.
* Major PCMCIA Cleanup to make code better readable and maintainable.
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.
* Fix timer problems on AMCC yucca board.
Set Timer Clock Select to use CPU clock as a timer input source.
* Bring yucca config more in line with other AMCC boards.
* Add AMCC bamboo board to MAKEALL build script.
* Fix AMCC bamboo eval board compilation errors.
* Add system memory to the PCI region list for AMCC PPC44x CPUs.
Enabled it for Yucca board.
* Cleanup config file and bootup output for Yucca board.
* Fix CONFIG_440_GX define usage.
* Remove autogenerated bmp_logo.h file.
* Add support for AMCC 440SPe CPU based eval board (Yucca).
* Call serial_initialize() before first debug() is used.
* Cleanup trab board for GCC-4.x
* VoiceBlue update: use new MTD flash partitioning methods, use more
reasonable TEXT_BASE, update default environment and enable keyed
autoboot.
Patch by Ladislav Michl, 16. Aug 2005
* Add forgotten changes for the PLEB 2 Board.
Patch by David Snowdon, 13. Aug 2005
* Add support for wrPPMC7xx/74xx boards
Patch by Richard Danter, 12 Aug 2005
* Add support for gth2 board
Patch by Thomas Lange, Aug 11 2005
* Add support for CONFIG_SERIAL_MULTI on MPC5xxx
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.
* Bugfix in I2C initialisation on S3C2400.
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, 04 Apr 2006
* Fix DDR6 errata on TQM834x boards
Patch by Thomas Waehner, 07 Mar 2006
* Remove obsolete flash driver board/tqm5200/flash.c
Patch by Martin Krause, 11 Jan 2006
* Update configuration for CMC-PU2 board
Patch by Martin Krause, 17 Nov 2005
* Add support for PS/2 keyboard on TQM85xx board
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
* Fix TRAB channel switching delay for trab_fkt.bin standalone applikation
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.
Patch by Martin Krause, 08 Nov 2005
* Adjust TQM5200 make targets
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
* Fix setting of environment variable "ver" on trab board
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
* Fix wrong usage of udelay() in led_blink() on trab board
Patch by Martin Krause, 27 Oct 2005

Patch by Scott McNutt, 08 Jun 2006
* Nios II - Add EPCS Controller bootrom work-around
-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.
Patch by Scott McNutt, 08 Jun 2006
