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)
