[PATCH 01/29] powerpc/85xx: Simplify P1020RDB CAMP dts using includes

Kumar Gala galak at kernel.crashing.org
Thu Nov 17 18:15:53 EST 2011


If we include the p1020rdb.dts instead of p1020si.dts we greatly reduce
duplication and maintenance.  We can just list which devices are
disabled for the given core and mpic protected sources.
