* Fixes for gcc 3.4 based m68k toolchain,
based on patch by Jate Sujjavanich.
+* Fix lowboot support on MCC200 board
+
+* Merged MPC8349ADS and MPC8349EMDS ports into MPC8349EMDS port:
+ - Removed MPC8349ADS port
+ - Added PCI support to MPC8349ADS
+ - reworked memory map to allow mapping of all regions with BATs
+ Patch by Kumar Gala 20 Apr 2006
+
+* Coding Style cleanup
+
+* Write RTC seconds first to maintain settings integrity per
+ Maxim/Dallas DS1306 data sheet.
+ Patch by Alan J. Luse, 02 May 2006
+
+* Scheduled for removal: strnicmp() which is unused
+
+* Update for Intel Monahans boards:
+ - support for magic key detection and handling on delta board
+ - NAND support for zylonite board + some minor cleanup
+
+* Declare load_serial_ymodem() when using CFG_CMD_LOADB.
+ Patch by Jon Loeliger, 01 May 2006
+
+* Fixed handling of bad checksums with "mkimage -l"
+
* Added support for BC3450 board
- Patch by Stefan Strobl, 21. Oct 2005
+ Patch by Stefan Strobl, 21 Oct 2005
* Update for NC650 board:
- Support rev1 and rev2 hardware
