This patch adds the possibility in both debug and ramfs modes to optionally load an env file from /tftpboot/$tftppath (this is ignored if not present, so the change is backward compatible). This gives the debug and ramfs scripts the possibility to set uboot environment variables that were previously asked the users to manually set (nfs path in debug and rootfs size in ramfs).
