+ HPE GXP is the name of the HPE Soc. This SoC is used to implement many
+ BMC features at HPE. It supports ARMv7 architecture based on the Cortex
+ A9 core. It is capable of using an AXI bus to which a memory controller
+ is attached. It has multiple SPI interfaces to connect boot flash and
+ BIOS flash. It uses a 10/100/1000 MAC for network connectivity. It
+ has multiple i2c engines to drive connectivity with a host
+ infrastructure.
