From 6f1eba49a558421e3fcb06ab0addc12b9a3804c6 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 12 Mar 2015 13:08:46 +0800 Subject: [PATCH] x86: Add ramboot and nfsboot commands in x86-common.h It is very common in the debug stage to test U-Boot loading a linux kernel. The commands to boot linux kernel with ramdisk and nfs as the root are common to all x86 targets, so it makes sense to add them as the U-Boot default environment in x86-common.h.
