Changes since U-Boot 1.1.4:
======================================================================
+* Added support for BC3450 board
+ Patch by Stefan Strobl, 21. Oct 2005
+
+* Update for NC650 board:
+ - Support rev1 and rev2 hardware
+ - adapt to new NAND layer
+ - add CP850 configuration based on NC650
+
+* MPC5200: enable snooping of DMA transactions on XLB even if no PCI
+ is configured; othrwise DMA accesses aren't cache coherent which
+ causes for example USB to fail.
+
+* Some code cleanup
+
+* Fix dbau1x00 boards broken by dbau1550 patch
+ PLL:s were not set for boards other than 1550.
+ Flash CFI caused card to hang due to undefined CFG_FLASH_BANKS_LIST.
+ Default boot is now bootp for cards other than 1550.
+ Patch by Thomas Lange, 10 Aug 2005
+
+* Fixes common/cmd_flash.c:
+ - fix some compiler/parser error, if using m68k tool chain
+ - optical fix for protect on/off all messages, if using more
+ then one bank
+ Patch by Jens Scharsig, 28 Jul 2005
+
+* Fix Quad UART mapping on MCC200 board due to new HW revision
+
+* Fix JFFS2 support for legacy NAND driver.
+
+* Remove dependencies between DoC code and old legacy NAND driver.
+
+* Fix PM828_PCI target, for which PCI was *not* configured in.
+
+* Fix Lite5200B support: initialize SDelay register
+ See Freescale's AN3221 "MPC5200B SDRAM Initialization and
+ Configuration", 3.3.1 SDelay--MBAR + 0x0190
+
+* Changes/fixes for drivers/cfi_flash.c:
+
+ - Add Intel legacy lock/unlock support to common CFI driver
+
+ On some Intel flash's (e.g. Intel J3) legacy unlocking is
+ supported, meaning that unlocking of one sector will unlock
+ all sectors of this bank. Using this feature, unlocking
+ of all sectors upon startup (via env var "unlock=yes") will
+ get much faster.
+
+ - Fixed problem with multiple reads of envronment variable
+ "unlock" as pointed out by Reinhard Arlt & Anders Larsen.
+
+ - Removed unwanted linefeeds from "protect" command when
+ CFG_FLASH_PROTECTION is enabled.
+
+ - Changed p3p400 board to use CFG_FLASH_PROTECTION
+
+ Patch by Stefan Roese, 01 Apr 2006
+
+* Changes/fixes for drivers/cfi_flash.c:
+ - Correctly handle the cases where CFG_HZ != 1000 (several
+ XScale-based boards)
+ - Fix the timeout calculation of buffered writes (off by a
+ factor of 1000)
+ Patch by Anders Larsen, 31 Mar 2006
+
+* Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)
+
+ 405 SDRAM: - The SDRAM parameters can now be defined in the board
+ config file and the 405 SDRAM controller values will
+ be calculated upon bootup (see PPChameleonEVB).
+ When those settings are not defined in the board
+ config file, the register setup will be as it is now,
+ so this implementation should not break any current
+ design using this code.
+
+ Thanks to Andrea Marson from DAVE for this patch.
+
+ 440 DDR: - Added function sdram_tr1_set to auto calculate the
+ TR1 value for the DDR.
+ - Added ECC support (see p3p440).
+
+ Patch by Stefan Roese, 17 Mar 2006
+
+* Fix CONFIG_SKIP_LOWLEVEL_INIT dependency in cpu/arm920t/start.S
+ Patch by Peter Menzebach, 13 Oct 2005 [DNX#2006040142000473]

+ Merge from Markus Klotzbücher's repo, 01 Apr 2006
+
+* GCC-4.x fixes: clean up global data pointer initialization for all
+ boards
+
+* Update for Delta board:
+ - redundant NAND environment
+ - misc Monahans cleanups (remove dead code etc.)
+ - DA9030 Initialization; some minimal changes to PXA I2C driver to
+ 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.

+* Add initial support for MPC8349E MDS board.
+
+* Add support for ECC DDR initialization on MPC83xx.

+
+* 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.

+
+* 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.

+
+* 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.

+ error bits if flash_status_check() returns ERR_TIMEOUT.

+
+* 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

+
+* 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.

+* Cleanup U-Boot boot messages on ARM.
+
+ To match the U-Boot user interface on ARM platforms to the U-Boot
+ standard (as on PPC platforms), some messages with debug character
+ 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.
