Florent Kermarrec 688dae0112 cores/spi: Add new SPIMMAP core allowing doing SPI accesses directly from MMAP. 
Implements a new SPIMMAP module, allowing accessing multiple SPI peripherals directly
from MMAP. It allows configurable SPI transactions: mode, bit order, and data width.

Developed and funded through a collaboration with MoTeC.

Example of integration:

# SPI MMAP ---------------------------------------------------------------------------------
spi_pads = Record([("clk", 1), ("cs_n", 8), ("mosi", 1), ("miso", 1)])
spi_mmap_tx_region = SoCRegion(origin=0x8000_0000, size=4096, cached=False)
spi_mmap_rx_region = SoCRegion(origin=0x8000_1000, size=4096, cached=False)
self.spi_mmap = SPIMMAP(
    pads          = spi_pads,
    data_width    = 32,
    sys_clk_freq  = sys_clk_freq,
    tx_origin     = spi_mmap_tx_region.origin,
    rx_origin     = spi_mmap_rx_region.origin,
    tx_fifo_depth = 32,
    rx_fifo_depth = 32,
)

self.bus.add_slave(name="spi_tx",
    slave  = self.spi_mmap.tx_mmap.bus,
    region = spi_mmap_tx_region,
)
self.bus.add_slave(name="spi_rx",
    slave  = self.spi_mmap.rx_mmap.bus,
    region = spi_mmap_rx_region,
)
self.irq.add("spi_mmap", use_loc_if_exists=True)
