[U-Boot] [PATCH] powerpc/P2041RDB: Fix Flash address LAW address

York Sun yorksun at freescale.com
Sat Oct 27 04:40:15 CEST 2012


P2041RDB uses common corenet TLB and LAW. However it doesn't have promjet
connector. It is necessary to use the same base address for correct LAW
address. An offset is added for NOR flash.
