Add documentation for In-Field Scan (IFS). This documentation describes the basics of IFS, the loading IFS image, chunk authentication, running scan and how to check result via sysfs. The CORE_CAPABILITIES MSR enumerates whether IFS is supported. The full github location for distributing the IFS images is still being decided. So just a placeholder included for now in the documentation. Future CPUs will support more than one type of test. Plan for that now by using a "_0" suffix on the ABI directory names. Additional test types will use "_1", etc. Reviewed-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> Reviewed-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20220506225410.1652287-13-tony.luck@intel.com Signed-off-by: Hans de Goede <hdegoede@redhat.com>
