From: Magnus Damm <damm+rene...@opensource.se>
Here's a simple prototype to get a basic IPMMU environment going on
the R-Car M3-N SoC on the r8a77965 Salvator-X board. IPMMU-MM and DS0/DS1
are used with SYS-DMAC that in turn may be used with SCIF for testing.
As based "renesas-drivers-next-2017-11-14-v4.14" is used with
[PATCH/RFC] arm64: r8a77965 Salvator-X SoC/board support prototype
This patch includes the following commits from renesas-bsp @ kernel.org
and in particular the recent "rcar-3.5.9.rc2" release:
