From 6c74274c8d2eec1e92e338ef197ffe210cc5b52d Mon Sep 17 00:00:00 2001 From: Gabor Juhos <juhosg@openwrt.org> Date: Sat, 7 Jan 2012 16:29:16 +0000 Subject: generic: improve MIPS kexec support It is based on patches from the linux-longsoon-community git tree: http://dev.lemote.com/cgit/linux-loongson-community.git/ Now the kernel can use the command line parameter from kexec-tools. Runtime tested on ar71xx with 2.6.39.4 (the wathdog must be stopped before executing the new kernel). Compile tested with lantiq (3.1.4) and brcm47xx (3.0.12).
