Subject: [PATCH 2/2] Documentation: add imx6ull-evk boot mode documentation
Date: Fri,  9 Aug 2019 14:29:43 +0200	[thread overview]
Message-ID: <20190809122943.2185-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20190809122943.2185-1-a.fatoum@pengutronix.de>

The compute module on the 6ULL-EVK has two DIP switches for choosing the
boot mode. Instead of looking them up in the vendor documentation[1] each
time, document them here.
