Subject: [PATCH v2] sh: ap325rxa: create CPLD data area in mtd
Date: Wed, 24 Sep 2008 02:46:48 +0000 [thread overview]
Message-ID: <48D9AA18.2070803@renesas.com> (raw)
AP320 and AP325RXA has CPLD data in NOR Flash.
If this area erased, this board can not boot.
This patch create CPLD data area and set writeable mask bit.
