  Changes since U-Boot 1.1.4:
  ======================================================================
  
 -  This is in order to fix issues with some USB sticks or knives timing
 -  out during initialisation. Some code readability improvements.
+ * Prevent USB commands from working when USB is stopped.
+ 
+ * Add rudimentary handling of alternate settings of USB interfaces.

 +* 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.
 +
 +* MCC200: set default configuration to low_boot DDR,
 +  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
 +
 +* Update NetStar board
 +  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
 +
 +* Add readline cmdline-editing extension
 +  Patch by JinHua Luo, 01 Sep 2005
 +
 +* Add support for friendly-arm SBC-2410X board
 +  Patch by JinHua Luo, 01 Sep 2005
 +
 +* Fix multi-part image support on i386 platform.
 +  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.
