We are not using the NOR flash anymore but the SD card because:

  1. the Zynq NOR flash controller is a pain.
  2. NOR flash seems relatively uncommon on Zynq boards, many have a SD card only.

We have a new configuration format based on a FAT filesystem. Currently it is read-only in the runtime.

Also support replacing boot.bin so that firmware can be updated over the network.

Note: both our SD card driver and the FAT library we use already support writing.

We could keep using the custom protocol in artiq_coremgmt (better UX for common use cases, and consistent with the NOR flash devices), or implement a FTP server.

Heuristic could be: if string is ASCII and 100 characters or less, then store in config.txt and remove /config/ file if it exists, otherwise store as file.
