[U-Boot-Users] [PATCH] ppc4xx: Unify AMCC's board config files (part 1/3)

Fri Jun 6 15:57:02 CEST 2008
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.
