Subject: [PATCH 0/3] of: Allow for const properties
Date: Wed, 31 Jan 2018 12:04:35 +0100 [thread overview]
Message-ID: <20180131110438.22620-1-s.hauer@pengutronix.de> (raw)
This series allows to unflatten a DTB while reusing the existing property
data from the DTB in the unflattened tree. This can make the memory
consumption much smaller when big properties are stored in the flattened
tree. While there's normally not much use of such an optimization
there's one user which profits from it: The FIT image code as FIT images
a only DTBs with kernel and ramdisk images stored in properties.
