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.
