Add support for Serial Peripheral interface (SPI) as a proper bus standard.
Includes an example device (m25p80 SPI flash), an example controller (Xilinx
XPS SPI) and adds it to all to a machine model (petalogix_ml605_mmu.c).
Patch 1 adds the Serial Peripheral Interface (SPI) protocol as a bus and
defines a QOM type for slave devices. The approach to doing this is based
looseley on the existing I2C QOMification.
Patch 2 is a device model for the m25p80 style SPI flash chip.
Patch 3 is the Xilinx XPS SPI contoller. Its a sysbus device that instantiates
a spi bus, and interfaces the two (as per the controllers functionality)
Patch 4 instantiates the XPS SPI controller in the petalogix ML605 reference
platform and connects one m25p80 to it.
Peter A. G. Crosthwaite (4):
SPI: initial support
m25p80: initial verion
xilinx_spi: initial version
petalogix-ml605: added spi controller with m25p80
