Subject: [PATCH 4/7] ARM: mvebu: move lowlevel code to lowlevel.c
Date: Mon, 23 Jun 2014 22:10:32 +0200 [thread overview]
Message-ID: <1403554235-12674-5-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <1403554235-12674-1-git-send-email-sebastian.hesselbarth@gmail.com>
mach-mvebu has two files containing lowlevel code. Consolidate both into
mach-mvebu/lowlevel.c. Also put the now empty mach-mvebu/common.c into
non-lowlevel obj-y as it will be used for common non-lowlevel code later.
