Subject: [PATCH 07/11] ARM: clep7212: Fix NULL pointer exception if MMU is enabled
Date: Fri, 8 Feb 2013 14:02:19 +0400 [thread overview]
Message-ID: <1360317743-25975-7-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1360317743-25975-1-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.
