From 7fbee0c7b2f6eebced44fd2060fbaac6fc5fd9e5 Mon Sep 17 00:00:00 2001 From: Andre Heider Date: Sat, 12 Sep 2020 09:32:41 +0200 Subject: [PATCH] mvebu: Add bootscript for espressobin to support mainline firmware 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.
