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.master
