Subject: [PATCH v2 1/2] ARM: dts: Add an am33xx include file for MLO size reduction
Date: Tue, 26 May 2015 15:23:10 +0200	[thread overview]
Message-ID: <1432646591-6991-1-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 6K.

Signed-off-by: Wadim Egorov <w.egorov@phytec.de>

v2:
	- rename file to am33xx-strip.dtsi
	- keep gpio* and uart* nodes
