Holger Brunck 2d9528e32f km/common: simplify default environment This is a first step to simplify the default environment. Move all the environment variables which are only needed for debugging purpose to textfiles in the scripts directory. In case of debugging these files can be loaded via tftp into RAM and set via the env import command. Other variables are identified as obsolete and were removed.

README

debug-common-env.txt
============================
This file defines environment variables which are valid for powerpc boards
and for arm boards.

addramfs: add phram device for the rootfilesysten in ram
develop: for development, laod kernel via tftp and mount  rootfs via NFS
nfsargs: default arguments for nfs boot
ramfs: load rootfilesystem in RAM  kernel
rootfsfile: loacation of the rootfs file for ramfs
setramfspram: compute PRAM size for ramfs target
setrootfsaddr: compute rootfilesystem address for phram
tftpkernel: load a kernel with tftp into ram
tftpramfs: load rootfs with tftp into ram

debug-ppc-env.txt
============================
fdt_file: location of the dtb file on the tftp server
tftpfdt: load dtb file and set fdt address

debug-arm-env.txt
============================
tftpfdt: for arm only a dummy variable, because we have no fdt on arm
