km/common: simplify debug environment
The debug environment which is stored in textfiles in the scripts directory was reworked. Two usecase are now present which can be executed simply from the default environment: run develop: this configures the environment to setup the rootfs via nfs run ramfs: this configures the environment to setup the rootfs in ram Each architecture now has a "arch" variable which is used to load the architecture specific debug scripts and to set the rootpath for NFS.

+These scripts are needed for our development usecases. Copy this directory
+into your tftp root directory to be able to use this scripts.
+cp -r <u-boot-repo>/board/keymile/scripts <your_tftp_root>/
+
+To load and configure these usecase, two environment variables in the u-boot
+default environment must be parsed:
+run develop : setup environment to configure for rootfs via nfs
+run ramfs : setup environment to configure for rootfs in ram
+
+Last change: 20.05.2011

+develop-common.txt
+============================
+This file defines variables for working with rootfs via nfs for powerpc and
+arm.
+
+develop-<arch>.txt
============================
-This file defines environment variables which are valid for powerpc boards
-and for arm boards.
+This file defines architecture specific variables for working with rootfs via
+nfs arm.
-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
+ramfs-common.txt
============================
-fdt_file: location of the dtb file on the tftp server
-tftpfdt: load dtb file and set fdt address
+This file defines variables for working with rootfs inside the ram for powerpc
+and arm.
-debug-arm-env.txt
+ramfs-<arch>.txt
============================
-tftpfdt: for arm only a dummy variable, because we have no fdt on arm
+This file defines architecture specific variables for working with rootfs inside
+ram.
