Subject: [PATCH 01/16] ARM: start: Allow to pass machine type as boarddata
Date: Wed, 18 Sep 2019 09:54:06 +0200	[thread overview]
Message-ID: <20190918075421.20456-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20190918075421.20456-1-s.hauer@pengutronix.de>

Allow to pass a machine type number as directly as boarddata. This makes
it easy for non device tree boards to pass a machine type and to
identify themselves during runtime.
