Subject: [PATCH 16/17] ARM: i.MX Phytec physom: convert to board driver
Date: Thu,  6 May 2021 11:29:00 +0200
Message-ID: <20210506092901.25461-17-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de>

Board driver is the new way for board specific fixups and the physom
board with its many compatible strings can really take profit from it,
so convert it.
