[PATCH v3 0/3] Add initial Thunder Bay SoC / Board support

[kenchappa.demakkanavar]

From: "Kenchappa, Demakkanavar" <kenchappa.demakkanavar@intel.com>

Hi,

This patch-set adds initial support for a new Intel Movidius SoC
code-named Thunder Bay. The SoC couples an ARM Cortex A53 CPU
with an Intel Movidius VPU.

This initial patch-set enables only the minimal set of components
required to make the Thunder Bay full or prime configuration boards
boot into initramfs.

Thunder Bay full configuration board has 4 clusters of 4 ARM
Cortex A53 CPUs per cluster, 4 VPU processors and
(8GB + 8GB + 4GB + 4GB) DDR memory.

Thunder Bay prime configuration board has 4 clusters of 4 ARM
Cortex A53 CPUs per cluster, 2 VPU processors and
(8GB + 4GB) DDR memory.

Changes since v2:
* Add compatibility strings for all supported boards in dt-binding yaml
* Email id format corrected. (First name, Last name)
* $nodename schema added for the root node
* Fixed 'make dtbs_check' warnings/errors
* Removed alias name for disabled serial1 node
* Corrected lowercase hex on unit-addresses

Changes since v1:
* Commit message updated for patch 3/3
* UART0 enabled by default for all Thunder Bay boards

Regards,
Kenchappa S. D.
