LiteSPI provides a small footprint and configurable SPI core.

LiteSPI is part of LiteX libraries whose aims are to lower entry level of complex FPGA cores by providing simple, elegant and efficient implementations of components used in today's SoC such as Ethernet, SATA, PCIe, SDRAM Controller...

Using Migen to describe the HDL allows the core to be highly and easily configurable.

LiteSPI can be used as LiteX library or can be integrated with your standard design flow by generating the verilog rtl that you will use as a standard core.
