From 3d6cb3b24add6415f86a0f013ea40f5639b90047 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Sat, 3 Nov 2007 12:08:28 +0100 Subject: [PATCH] ppc4xx: Add AMCC Kilauea/Haleakala NAND booting support This patch adds NAND booting support for the AMCC 405EX(r) eval boards. Again, only one image supports both targets.
