To allow offline installation, the "liteiclink" package has to be installed before the "liteeth" package. Otherwise, to satisfy the dependency requirements, the setup will attempt to download the "liteiclink" package from the internet and will consequently fail.

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)
