Subject: [PATCH 2/6] of: make of_add_memory available for other board
Date: Wed, 13 Feb 2013 11:06:40 +0100 [thread overview]
Message-ID: <1360750004-17713-2-git-send-email-plagnioj@jcrosoft.com> (raw)
In-Reply-To: <1360750004-17713-1-git-send-email-plagnioj@jcrosoft.com>
so when the first stage booloader of firmware provide the dtb
we can use it to probe the memory
also allow to print what we probe
