LiteX (https://github.com/enjoy-digital/litex) is a SoC framework
that targets FPGAs. LiteSDCard is a small footprint, configurable
SDCard core commonly used in LiteX designs.

The driver was first written in May 2020 and has been maintained
cooperatively by the LiteX community. Thanks to all contributors!

I remembered I still owe you an answer on whether this was ever
successfully tested as a module: The answer is *yes* -- if configured
as a loadable module, it loads OK with modprobe, works fine, and can
be unloaded (with `modprobe -r`) and re-loaded indefinitely.

Very good.

Thanks for following up on the suggestions I made.
