Subject: [PATCH V3 03/10] ARM: sirf: drop MARCO support in reset controller module
Date: Sat, 3 Jan 2015 16:27:37 +0800 [thread overview]
Message-ID: <1420273664-10438-4-git-send-email-21cnbao@gmail.com> (raw)
In-Reply-To: <1420273664-10438-1-git-send-email-21cnbao@gmail.com>
From: Barry Song <Baohua.Song@csr.com>
MARCO will not be supported any more. it has been replaced by CSR
atlas7.
