Subject: [PATCH 6/8] ARM: Use function specific sections in assembly functions
Date: Tue, 18 Feb 2020 16:39:15 +0100	[thread overview]
Message-ID: <20200218153917.15937-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200218153917.15937-1-s.hauer@pengutronix.de>

To let the linker remove unused functions we have to make sure all
functions are in separate sections. Fix this for several forgotten
functions.
