From: Nick Hawkins <nick.hawk...@hpe.com>
The HPE SoC is new to linux. A basic device tree layout with minimum
required for linux to boot including a timer and watchdog support has
been created.
The dts file is empty at this point but will be updated in subsequent
updates as board specific features are enabled.
