    make it work with the Monahans.
  - Make Monahans clock frequency configurable using
    CFG_MONAHANS_RUN_MODE_OSC_RATIO and
    CFG_MONAHANS_TURBO_RUN_MODE_RATIO.
  Merge from Markus Klotzb點her's repo, 25 Mar 2006

* Enable Quad UART om MCC200 board.

* Cleanup MCC200 board configuration; omit non-existent stuff.

* Fix DDR ECC bit definitions for MPC83xx.

* Add initial support for MPC8349E MDS board.

* Add support for ECC DDR initialization on MPC83xx.

* Add DMA support for MPC83xx.

* Add sync in do_reset() routine for MPC83xx after RPR register
  was written to. It is need on some targets when BAT translation
  is enabled.

* Add bit definitions for MPC83xx DDR controller registers.

* Add Dcbz(), Dcbi() and Dcbf() routines for MPC83xx.

* Correct shift offsets in icache_status and dcache_status for MPC83xx.

  Patch by  Patch by Jose Maria (Txema) Lopez, 16 Jan 2006

* Apply SoC concept to arm926ejs CPUs, i.e. move the SoC specific
  timer and cpu_reset code from cpu/$(CPU) into the new
  cpu/$(CPU)/$(SOC) directories
  Patch by Andreas Engel, 13 Mar 2006

* Change max size of uncompressed uImage's to 8MByte and add
  CFG_BOOTM_LEN to adjust this setting.

  As mentioned by Robin Getz on 2005-05-24 the size of uncompressed
  uImages was restricted to 4MBytes. This default size is now
  increased to 8Mbytes and can be overrided by setting CFG_BOOTM_LEN
  in the board config file.

  Patch by Kumar Gala, 12 Jan 2006

* Report back PCI bus when doing table based device config
  Patch by Kumar Gala, 11 Jan 2006

* Added support for PCI prefetchable region and BARs
  If a host controller sets up a region as prefetchable and
  a device's BAR denotes it as prefetchable, allocate the
  BAR into the prefetch region.

  been setup by the controller we fall back to allocating
  the BAR into the normally memory region.

* Word alignment fixes for word aligned NS16550 UART
  Patch by Jean-Paul Saman, 01 Mar 2005

  Fixes bug with UART that only supports word aligned access: removed
  "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" some
  (broken!) versions of GCC generate byte accesses when encountering
  the packed attribute regardless if the struct is already correctly
  aligned for a platform. Peripherals that can only handle word
  aligned access won't work properly when accessed with byte access.
  The struct NS16550 is already word aligned for REG_SIZE = 4, so
  there is no need to packed the struct in that case.

* Fix behaviour if gatewayip is not set
  Patch by Robin Gilks, 23 Dec 2004

* Fix cleanup for netstart board.
  Remove build results from repository

* Some code cleanup for GCC 4.x

  (This is Work in Progress!)

* Add support for TQM8260-AI boards.

* Minor code cleanup

* Merge the new NAND code (testing-NAND brach); see doc/README.nand
  Rewrite of NAND code based on what is in 2.6.12 Linux kernel
  Patch by Ladislav Michl, 29 Jun 2005

* Add lowboot target to mcc200 board
  Patch by Stefan Roese, 4 Mar 2006

* Fix problem with flash_get_size() from CFI driver update
  Patch by Stefan Roese, 1 Mar 2006

* Make CFG_NO_FLASH work on ARM systems
  Patch by Markus Klotzbuecher, 27 Feb 2006

* Update mcc200 config: Disable PCI and DoC, use 133 MHz IPB clock,
  use hush shell.

* Convert mcc200 to use common CFI flash driver
  Patch by Stefan Roese, 28 Feb 2006

* Add env-variable "unlock" to handle initial state of sectors
  (locked/unlocked).

  Only the U-Boot image and it's environment is protected,
  all other sectors are unprotected (unlocked) if flash
  hardware protection is used (CFG_FLASH_PROTECTION) and
  the environment variable "unlock" is set to "yes".

  Patch by Stefan Roese, 28 Feb 2006

* Update drivers/cfi_flash.c:
  - find_sector() called in both versions of flash_write_cfiword()
  Patch by Peter Pearse, 27th Feb 2006

* CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode
  Patch by Jose Maria Lopez, 16 Jan 2006

* Add support for AMD/Spansion Flashes in flash_write_cfibuffer
  Patch by Alex Bastos and Thomas Schaefer, 2005-08-29

* Changes/fixes for drivers/cfi_flash.c:
  We *should* check if there are any error bits if the previous call
  returned ERR_OK (Otherwise we will have output an error message in
  flash_status_check() already.)  The original code would only check for
  error bits if flash_status_check() returns ERR_TIMEOUT.
  Patch by Marcus Hall, 23 Aug 2005

* Changes/fixes for drivers/cfi_flash.c:
  - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c
  - Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c
  Patch by Sangmoon Kim, 19 Aug 2005

* Fixes for drivers/cfi_flash.c:
  - Fix wrong timeout value usage in flash_status_check()
  - Round write_tout up when converting to msec in flash_get_size()
  - Remove clearing flash status at the end of flash_write_cfibuffer()
    which sets Intel 28F640J3 flash back to command mode on CSB472
  Patch by Tolunay Orkun, 02 July 2005

* Add basic support for the SMMACO4 Board from PanDaCom.
  Patch by Heiko Schocher, 20 Feb 2006

* Add GIT version information (commid ID) to untagged U-Boot versions

  As done in the linux kernel, the U-Boot version (U_BOOT_VERSION)
  of all unreleased (untagged) U-Boot images will be automatically
  extended upon compiletime with a part of the GIT commit ID and
  possibly with "dirty" if uncommited changes are detected.

  Here an example for the resulting version:
  "U-Boot 1.1.4-g3457ac18-dirty"

  The version is now maintained in the toplevel Makefile and the
  version headers are autogenerated.

  are removed from the default U-Boot build.
  Enable DEBUG for lib_arm/board.c to enable debug messages.
  New CONFIG_DISPLAY_CPUINFO and CONFIG_DISPLAY_BOARDINFO options.
  Patch	 by Stefan Roese, 24 Jan 2006
