From fd671802b67a0ef37a06124fa2ce85f00aa22c6f Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 11 Oct 2007 11:15:59 +0200 Subject: ppc4xx: Enable device tree support (fdt) on Kilauea per default This patch enables the fdt support on the AMCC Kilauea eval board. Additionally now EBC ranges fdt fixup is included to support NOR FLASH mapping via the Linux physmap_of driver. This Kilauea port now support booting arch/ppc and arch/powerpc Linux kernels. The default environment "net_nfs" is for arch/ppc and "net_nfs_fdt" is for arch/powerpc. In the long run, arch/ppc support will be removed.
