Subject: [PATCH v1] MIPS: bcm47xx: migrate to multiimage
Date: Mon, 17 Dec 2018 12:02:06 +0100	[thread overview]
Message-ID: <20181217110206.16269-1-o.rempel@pengutronix.de> (raw)

dlink-dir-320 has no meaning full lowlevel init, so add
a generic one. This should be enough to use it as second stage
loader with multiimage support.
