Subject: [PATCH 2/2] arm64: dts: Reduce size of virtio block device for foundation model
Date: Fri, 20 Dec 2013 12:52:44 +0000 [thread overview]
Message-ID: <1387543964-15057-2-git-send-email-broonie@kernel.org> (raw)
In-Reply-To: <1387543964-15057-1-git-send-email-broonie@kernel.org>
From: Mark Brown <broonie@linaro.org>
Will Deacon observed that kvmtool uses a size of 0x200 for virtio
block memory region and that the virtio block spec only uses 31 bytes in
the device specific region at 0x100 so reduce the region to a less
wasteful 0x200.
