Subject: [PATCH 1/2] ARM: dts: Add an am33xx include file for MLO size reduction
Date: Fri, 22 May 2015 14:09:14 +0200 [thread overview]
Message-ID: <1432296555-48594-1-git-send-email-w.egorov@phytec.de> (raw)
AM335x's MLO size limit is 109K.
The am33xx.dtsi file adds spare and never used nodes to the dtb.
With this patch we add a file to remove the unused nodes and reduce the
size of the dtb.
Including this file will reduce the lzo packed MLO size about 8K.
