Subject: [PATCH 08/10] video: Add screen_size field
Date: Wed, 18 Dec 2013 16:42:40 +0100	[thread overview]
Message-ID: <1387381362-7780-9-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1387381362-7780-1-git-send-email-s.hauer@pengutronix.de>

barebox does not need the screen size directly, but we pass the
framebuffer to Linux via simnplefb it is desirable to pass the
full size of the framebuffer. Default to calculated values from
the screen resolution.
