---------------------------------------------------------------------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.cSycamore/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.August 01 2005, Stefan Roese <sr@denx.de>
