Subject: [PATCH v1 00/19] Introduce Nuvoton Arbel NPCM8XX BMC SoC

This patchset  adds initial support for the Nuvoton 
Arbel NPCM8XX Board Management controller (BMC) SoC family. 

The Nuvoton Arbel NPCM8XX SoC is a fourth-generation BMC.
The NPCM8XX computing subsystem comprises a quadcore ARM 
Cortex A35 ARM-V8 architecture.

This patchset adds minimal architecture and drivers such as:
Clocksource, Clock, Reset, and WD.

Some of the Arbel NPCM8XX peripherals are based on Poleg NPCM7XX.

This patchset was tested on the Arbel NPCM8XX evaluation board.
