Subject: [PATCH 03/12] ARM: i.MX53: Detect booting from USB
Date: Mon, 4 Jul 2016 11:27:30 +0200 [thread overview]
Message-ID: <1467624459-16448-4-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1467624459-16448-1-git-send-email-s.hauer@pengutronix.de>
The USB download mode can be detected by reading the BMOD[0|1]
bits. Add support for it.
