This patch series unifies the AMCC eval board ports by introducing a common include header for all AMCC eval boards: include/configs/amcc-common.h This header now includes all common configuration options/defines which are removed from the board specific headers. The reason for this is ease of maintenance and unified look and feel of all AMCC boards. Signed-off-by: Stefan Roese <sr@denx.de>
