Quoting part of original message from eefb5f741015 commit in
linux-firmware repository:
This adds the "minifw" version of the EIP197 firmware, which the inside-
secure driver will use as a fallback if the original full-featured
firmware cannot be found. This allows for using the inside-secure driver
and hardware without access to "official" firmware only available under
NDA.
