Subject: [PATCH 3/3] USB: remove blackfin support
Date: Wed, 11 Sep 2019 09:26:49 +0200 [thread overview]
Message-ID: <20190911072649.19017-3-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20190911072649.19017-1-s.hauer@pengutronix.de>
The blackfin architecture has been removed from barebox. Remove the
blackfin specifics in the USB drivers as well.
