Subject: [PATCH v2 1/4] imx-usb-loader: Skip unknown tags
Date: Wed, 17 Sep 2014 12:25:09 +0200 [thread overview]
Message-ID: <1410949512-16562-2-git-send-email-s.trumtrar@pengutronix.de> (raw)
In-Reply-To: <1410949512-16562-1-git-send-email-s.trumtrar@pengutronix.de>
From: Sascha Hauer <s.hauer@pengutronix.de>
Instead of bailing out skip unknown tags. These tags are usually
doing operations to poll for a certain register state. The correct
solution is to implement this register polling, but for now delay
execution for a while and assume the register has the correct
state afterwards.
