Subject: [PATCH] FIT: Use const dtb unflatten variant
Date: Wed, 31 Jan 2018 12:13:28 +0100 [thread overview]
Message-ID: <20180131111328.8000-1-s.hauer@pengutronix.de> (raw)
This reduces the memory usage of the FIT image support. Instead of copying
the image from the DTB to the unflattened tree we let the unflattened tree
reference the data from the DTB.
