I reorganized my config files, putting the common stuff into netstal-common.h (got the idea by looking a amcc-common.h from Stefan). Added stuff to boot the new powerpc linux via NFS (only tested with HCU4). Signed-off-by: Niklaus Giger <niklaus.giger@netstal.com> Signed-off-by: Stefan Roese <sr@denx.de>
