Eliminates the CONFIG_MPC8560 option entirely. Distributes the
new CONFIG_CPM2 option to each 8260 board.
+* Patch by Stefan Roese, 01 Aug 2005:
+ - Major cleanup for AMCC eval boards Walnut, Bubinga, Ebony, Ocotea
+ (former IBM eval board). Please see "doc/README.AMCC-eval-boards-cleanup"
+ for details.
+ - Sycamore (PPC405GPr) eval board added (Walnut port is extended
+ to run on both 405GP and 405GPr eval boards).
+
+* Patch by Steven Blakeslee, 27 Jul 2005:
+ - Add support for AMCC PPC440EP/GR.
+ - Add support for AMCC Yosemite PPC440EP eval board.
+ - Add support for AMCC Yellowstone PPC440GR eval board.
+
+* Minor fixes for PPChameleon Board:
+ - fix alignment of NAND size
+ - make code do what the comment says
+
+* Implement h/w sector protection status synchronization at boot.
+ The code is provided for, and was tested on, the Yukon/Alaska
+ and PM520 boards only.
+
+ A bug in flash_real_protect() for the Yukon board was fixed by
+ adding a function that tells if two banks are on one flash chip.
+
* Fix sysmon POST problem: check I2C error codes
This fixes a problem of displaying bogus voltages when the voltages
are so low that the I2C devices start failing while the rest of the

+---------------------------------------------------------------------
+Cleanup of AMCC eval boards (Walnut/Sycamore, Bubinga, Ebony, Ocotea)
+---------------------------------------------------------------------
+
+Changes to all AMCC eval boards:
+--------------------------------
+
+o Changed u-boot image size to 256 kBytes instead of 512 kBytes on most
+ boards.
+
+o Use 115200 baud as default console baudrate.
+
+o Added config option to use redundant environment in flash. This is also
+ the default setting. Option for environment in nvram is still available
+ for backward compatibility.
+
+o Merged board specific flash drivers to common flash driver:
+ board/amcc/common/flash.c
+
+
+Sycamore/Walnut (one port supporting both eval boards):
+-------------------------------------------------------
+
+o Cleanup to allow easier "cloning" for different (custom) boards:
+
+ o Moved EBC configuration from board specific asm-file "init.S"
+ using defines in board configuration file. No board specific
+ asm file needed anymore.
