Subject: [PATCH/RFC 00/02] ARM: shmobile: r8a7795 Salvator-X IPMMU 4 GiB RAM test code
Date: Mon, 18 Jan 2016 14:48:17 +0900 [thread overview]
Message-ID: <20160118054817.22156.6531.sendpatchset@little-apple> (raw)
ARM: shmobile: r8a7795 Salvator-X IPMMU 4 GiB RAM test code
[PATCH/RFC 01/02] iommu/ipmmu-vmsa: Use 64-bit masks
[PATCH/RFC 02/02] arm64: dts: Salvator-X: Enable 4 GiB of RAM
This code simply enables 4 GiB of RAM on Salvator-X after
adjusting the IPMMU driver to tell the Linux driver model
that the device it is managing is able to do 64-bit bus
mastering.
Not for upstream merge. Patch 1/2 will be rolled into a larger
series for the IPMMU driver in the future. Patch 2/2 depends
on firmware updates, so the integration needs to be correctly
ordered to keep things smooth.
