Subject: [PATCH v2 6/9] ARM: clep7212: Fix NULL pointer exception if MMU is enabled
Date: Wed, 13 Feb 2013 15:41:41 +0400 [thread overview]
Message-ID: <1360755704-24105-6-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1360755704-24105-1-git-send-email-shc_work@mail.ru>
NOR-flash is placed at address 0x0, so if MMU is turned on, initialization
will fails. This patch fix this problem.
