GXP is the name of the HPE SoC.
This SoC is used to implement BMC features of HPE servers
(all ProLiant, Synergy, and many Apollo, and Superdome machines)
It does support many features including:
	ARMv7 architecture, and it is based on a Cortex A9 core
	Use an AXI bus to which
		a memory controller is attached, as well as
                 multiple SPI interfaces to connect boot flash,
                 and ROM flash, a 10/100/1000 Mac engine which
                 supports SGMII (2 ports) and RMII
		Multiple I2C engines to drive connectivity with a host infrastructure
		A video engine which support VGA and DP, as well as
                 an hardware video encoder
		Multiple PCIe ports
		A PECI interface, and LPC eSPI
		Multiple UART for debug purpose, and Virtual UART for host connectivity
		A GPIO engine
This Patch Includes:
	Documentation for device tree bindings
	Device Tree Bindings
	GXP Timer Support
	GXP Architecture Support

All new bindings must be in the DT-schema format (yaml files).
This enables a lot of syntax checks and validation.

We are slowly migrating away from the .txt based bindings.

Also, for new bindings please follow the guide lines listed in
Documentation/devicetree/bindings/submitting-patches.rst

Consider including the bindings with the drivers using the bindings so
things have a more natural split.
