Florent Kermarrec 41fe7cae0b core/spi: add minimal SPISlave 2019-08-29 09:46:20 +02:00
Florent Kermarrec 4990bf33c0 soc/core: simplify/cleanup HyperRAM core
- rename core to hyperbus.
- change layout (cs_n with variable length instead of cs0_n, cs1_n).
- use DifferentialOutput when differential clock is used.
- add test (python3 -m unittest test.test_hyperbus).

Usage example:
from litex.soc.cores.hyperbus import HyperRAM
self.submodules.hyperram = HyperRAM(platform.request("hyperram"))
self.add_wb_slave(mem_decoder(self.mem_map["hyperram"]), self.hyperram.bus)
self.add_memory_region("hyperram", self.mem_map["hyperram"], 8*1024*1024)

Florent Kermarrec 769d15d433 cores/spi: move CSR control/status to add_control method, add loopback capability and simple xfer loopback test
Moving control/status registers to add_control method allow using SPIMaster directly with exposed signals.
Add loopback capability (mostly for simulation, but can be useful on hardware too).

Florent Kermarrec 67159349d6 soc/interconnect: remove axi_lite
axi_lite code was defining AXI4Lite signals and doing a AXI4Lite bridge to the
CSR bus when LiteX was not having proper AXI support. LiteX now has  proper AXI
support and it also cover what axi_lite was doing: To create a AXILite to CSR
bus, user can create an AXILite2Wishbone bridge and then connect the CSR bus
directly to the wishbone bus as done in the others non-AXI SoC.
