From 7b2268b88fb9a67b13563fa61b8ae282b9aa6e00 Mon Sep 17 00:00:00 2001 From: Gerlando Falauto Date: Mon, 27 Jan 2014 16:58:27 +0100 Subject: [PATCH] arm/km: enable FDT for km_kirwkood This consists of: a) Defining the addresses, enabling fdtsupport [arm] b) Defining "cramfsloadfdt" [arm,powerpc => common] c) Adding the FDT address to bootm [arm,powerpc => common] d) Defining "tftpfdt" in ramfs-,develop- [arm,powerpc >= common] This should work with 3.10 kernels, whether loaded through TFTP (with rootfs either through NFS or TFTP-ramfs) or from the NAND. The machid was left unchanged, this should keep compatibility with both older and newer kernels.
