Parse and present Intel FSP (Firmware Support Package) information

fspinfo

fspinfo is a library and command line to parse and present FSP information.

NOTE: fspinfo is now part of the fiano framework. Find it under cmds/fspinfo. So this repository is now deprecated and read-only.

Intel FSP specification 2.0 can be found at https://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/fsp-architecture-spec-v2.pdf .
