Subject: [PATCH 1/2] mvme147: fix ram size in comment
Date: Thu, 5 Jun 2014 11:01:21 +0800 [thread overview]
Message-ID: <1401937282-18345-2-git-send-email-akong@redhat.com> (raw)
In-Reply-To: <1401937282-18345-1-git-send-email-akong@redhat.com>
The order of ram pages is 3, so the ram size is 2^3 * 4K = 32K.
