======================================================================
Changes since U-Boot 1.1.4:
======================================================================
* Fix dbau1x00 Board
- Fix dbau1x00 boards broken by dbau1550 patch
* 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 Aug 10 2005
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 July 2005
Patch by Jens Scharsig, 28 Jul 2005
* Fix Quad UART mapping on MCC200 board due to new HW revision
