[PATCH] Merge Yosemite & Yellowstone board ports
Now the AMCC eval boards Yosemite (440EP) and Yellowstone (440GR) share one config file and all board specific files. This way we don't have to maintain two different sets of files for nearly identical boards. Signed-off-by: Stefan Roese <sr@denx.de>
