Add 1T1R support to gateware/software. #29

Closed enjoy-digital closed 4 days ago

enjoy-digital commented 1 week ago

Will allow reducing PCIe bandwidth (and higher samplerates in 1T1R PCIe Gen2 X1) and sample processing/copy in SoapySDR.

Support was already partially in place and https://github.com/enjoy-digital/litex_m2sdr/commit/fa8ea4646c0609ffefb52a555449e5c90a0fde4d make it functionnal at build time when _1T1R_MODE is defined. This a first step before making it dynamically configurable. This indeed half PCIe bandwidth and allow higher samplerates when mounted in the baseboard.

This is now done with recent changes.
