Allow programming of the firmware SPI flash. Will probably need to autodetect firmware vs. bitstream vs. OS files

Could potentially use UF2 file format: https://github.com/microsoft/uf2

Would make it very easy to tell what is/isn't firmware, gives the file size, includes a checksum, etc.

Yes, this looks pretty nice. You could even use extension tags for a SHA2 checksum and to have a custom identifier for different types of files.
