kirill9617 / Luna - History

ci/test: add the ability to launch all unit tests with tox

python: standardize on the `luna` software being lowercase

LUNA = name of the project; hardware boards are branded LUNA
luna = name of the toolkit for building USB-related gateware

SPI: improvements to SPI hardware and testing; and minor fixes

gateware: update to a Trellis version with psuedo-differential outputs

This Trellis patch was made specifically for this use case, after we
manually identified the bitstream changes we needed. Thanks, Dave! :)

pre r0.2 -- minor improvements and debug fixes

- add silkscreen connector diagrams
- added test points for clock and voltage rails
- moved SPI connectors for reduced via density (DFM)
- added chip select for debug SPI

gateware: add enough of the PSRAM interface to smoke test it
