Subject: [PATCH 12/14] pcm030: fix /dev/self0 and /dev/env0
Date: Tue, 27 Sep 2011 10:28:27 +0200 [thread overview]
Message-ID: <1317112109-23311-13-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1317112109-23311-1-git-send-email-s.hauer@pengutronix.de>
/dev/self0 and /dev/env0 are in the last MB of nor flash. The
offset depends on the size of the flash, so detect this at
runtime.
