The generic bootscript is tailored around a downstream firmware and doesn't work on a firmware built from mainline components. Add a bootscript which: * sets $console since mainline u-boot doesn't do that * uses distro boot variables, so OpenWRT can be booted off any supported device when using a mainline firmware * sets missing distro boot variables for the downstream firmware Booting with a downstream firmware is unchanged. Booting with a mainline firmware now works. Signed-off-by: Andre Heider <a.heider@gmail.com>
