Changes since U-Boot 1.1.4:
======================================================================
+* Major PCMCIA Cleanup to make code better readable and maintainable.
+ Notes:
+ - Board-dependend code for RPXLITE and RPXCLASSIC-based boards
+ placed to the drivers/rpx_pmcia.c file to avoid duplication.
+ Same for TQM8xx-based boards (drivers/tqm8xx_pmcia.c).
+ - drivers/i82365.c has been split into two parts located at
+ board/atc/ti113x.c and board/cpc45/pd67290.c (ATC and CPC45 are
+ the only boards using CONFIG_82365).
+ - Changes were tested for clean build and *very* *few* boards.
+
* Fix timer problems on AMCC yucca board.
Set Timer Clock Select to use CPU clock as a timer input source.
