    2020Various Gateworks boards support 3.3V TTL SPI to an off-board expansion connector with a single CS#:

Drivers that use full-duplex transactions can be modified to support half-duplex (see [https://github.com/Gateworks/linux-newport/commit/cb270339619ccf2b50dfd3604a03626f85830453 'can:mcp251x: convert driver to half-duplex SPI'] as en example.
