Subject: [PATCH]NUC900 add gpio virtual memory map
Date: Tue, 2 Feb 2010 14:28:39 +0900 [thread overview]
Message-ID: <71413c851002012128l26bbf64fvfffabcae194f076e@mail.gmail.com> (raw)
hi, Dear Wan
This patch adds the gpio registers virtual memory map.
Without it, the gpio access will cause the "Data Abort" due to no
virtual memory assign to it.
