Subject: [PATCH 2/4] s3c64xx-add-srom-physical-virtual-mapping.patch
Date: Tue, 29 Dec 2009 14:40:30 +0000 [thread overview]
Message-ID: <20091229144030.15524.91370.stgit@hit-nxdomain.opendns.com> (raw)
In-Reply-To: <20091229143756.15524.25160.stgit@hit-nxdomain.opendns.com>
This adds the physical address of the SROM unit, and
applies a virtual mapping for it to the S3C_VA_MEM
slot.
