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. Signed-off-by: Nick Hawkins <nick.hawkins@hpe.com>
