Annapurna Labs(TM) is a technology company providing innovative solutions
including chips, software, and systems for the datacenter and enterprise
infrastructure.

Alpine(TM) is one of Annapurna Labs’ chip products targeting storage and
networking applications. It is a complete Platform-On-Chip,
integrating 2-4 cortex-A15 cores and multiple innovations to provide
a seamless networking and storage fabric for enterprise and datacenter
equipment.

This patchset provides initial support for the Alpine platform.

Patch #1 contains minimal, single-cpu architecture support.

Patch #2 adds early-debug capabilities via Alpine UART 0.

Patch #3 adds smp-support and a secondary cpu enable-method for the platform.

Patch #4 provides documentation for the available device-tree nodes.

Patch #5 provides a device-tree for Alpine soc and development board.

The patchset was tested with multi_v7_defconfig, adding CONFIG_ARCH_ALPINE

V2:
* map physical cpu-id from logical on cpu wakeup
* use syscon/regmap for sysfabric_service implementation
* devicetree format:
**  split between .dtsi and dts
**  dual license
**  node and manufacturer naming
* intoduce devicetree in two separate patches
* multiple format fixes
* rebased on d932006 (for-next)

---
V3:
* small format changes
* rebased on f9db7e2 (for-next)
