[Xen-devel] [PATCH 0/6] Initial Tegra platform support

[Chris Patterson <cjp256@xxxxxxxxx>]

The attached patch-set adds support for 32-bit and 64-bit Tegra SoCs; including
support for the Jetson TK1 and Jetson TX1 boards, as well as the Pixel C tablet.
Previous revisions have been tested against the TK1, TX1, and Pixel C.  This
current patch set has only been tested against the TX1 due to my curent hardware
availability, but should be OK on the other platforms.

Many thanks to Ian Campbell, whose original Jetson TK1 patchset contained a lot
of pointers in the right direction, and helped us to get started on this one!

This patch set includes:
  - A minor serial quirk to get the NS16550 on the Tegra working.
  - Support for the Tegra Legacy Interrupt Controller, which is necessary to get
    interrupt routing working correctly on Tegra devices. In this version of the
    patchset, the interrupt controller is supported via platform quirks.
  - A few additional minor features and logic fixes to support the Tegra. An
    example would be the Tegra-specific reset logic.

This patch set does NOT include:
  - Support for the Tegra-specific IOMMU. This means this platform doesn't yet
    support device passthrough.

This patch set includes fixes and cleanup requested from the original RFC
posted by Kyle Temkin. Kyle has done most of the authoring on this, but I am
picking it up to address the RFC reviews and push it though.

Chris Patterson (6):
  xen/arm: platforms: Add earlyprintk and serial support for Tegra
    boards.
  xen/arm: domain_build: Inherit GIC's interrupt-parent from host device
    tree
  xen/arm: Allow platforms to hook IRQ routing
  xen/arm: platforms: Add Tegra platform to support basic IRQ routing
  xen/arm: Add function to query IRQ 'ownership'
  xen/arm: platforms/tegra: Ensure the hwdom can only affect its own
    interrupts
