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.
