Changes since U-Boot 1.1.4:
======================================================================
* Add command for handling DDR ECC registers on MPC8349EE MDS board.
* 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.
* Add support for DS1374 RTC chip.
* Add support for Lite5200B board.
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 Stefan Roese, 13 Mar 2006
* Fix problem with updated PCI code in cpu/ppc4xx/405gp_pci.c
Patch by Stefan Roese, 13 Mar 2006

Patch by Cedric Vincent, 06 Jul 2005
* au1x00_eth.c: check malloc return value and abort if it failed
Patch by Andrew Dyer, 26 Jul 2005
* Change the sequence of events in soft_i2c.c:send_ack() to keep from
incorrectly generating start/stop conditions on the bus.
Patch by Andrew Dyer, 26 Jul 2005
* Fix bug in [id]cache_status commands for MPC85xx processors;
should look at LSB of L1CSRn registers to determine if L1 cache is
enabled, not the MSB.
Patch by Murray Jensen, 19 Jul 2005

* Fixed defines for MPC83xx SICRL register to match current specs

Patch by Kumar Gala 11 Jan 2006
* Allow board code to fixup the flat device tree before booting a
kernel
Patch by Kumar Gala 11 Jan 2006
* Added CONFIG_ options for bd_t and env in flat dev tree
CONFIG_OF_HAS_BD_T will put a copy of the bd_t
into the resulting flat device tree.

variables from u-boot into the flat device tree
Patch by Kumar Gala 11 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.
If a BAR is prefetchable and no prefetchable region has
been setup by the controller we fall back to allocating
the BAR into the normally memory region.
Patch by Kumar Gala 11 Jan 2006
* Only disable the MPC83xx watchdog if its enabled out of reset.
If its disabled out of reset SW can later enable it if so desired

Patch by Friedrich Lobenstock, 02 Jun 2005
* Fix comment in common/soft_i2c.c
Patches by Peter Korsgaard/Tolunay Orkun, 26 May 2005
* Cleanup compiler warnings.
Patch by Greg Ungerer, 21 May 2005
* 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
* Fixes to support environment in NAND flash;
enable NAND flash based environment for delta board.
* Add support for Intel Monahans CPU on Zylonite and Delta boards
(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.
