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