Subject: [PATCH 03/14] bootm: introduce bootm_get_os_size
Date: Fri, 22 Jan 2016 08:32:21 +0100	[thread overview]
Message-ID: <1453447952-30818-4-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1453447952-30818-1-git-send-email-s.hauer@pengutronix.de>

ARM do_bootm_linux is not only called with uImages but also with
raw images, so we can't use uimage_get_size() here. Introduce
bootm_get_os_size() which handles the different image types.
