Add SPI Driver to HPE GXP Architecture Merge series from nick.hawkins@hpe.com <nick.hawkins@hpe.com>: The GXP supports 3 separate SPI interfaces to accommodate the system flash, core flash, and other functions. The SPI engine supports variable clock frequency, selectable 3-byte or 4-byte addressing and a configurable x1, x2, and x4 command/address/data modes. The memory buffer for reading and writing ranges between 256 bytes and 8KB. This driver supports access to the core flash and bios part.
