Subject: [PATCH RFC 0/4] Add firmware signature file check

Hi,

this is a patch series to add the support for firmware signature
check.  At this time, the kernel checks extra signature file (*.sig)
for each firmware, instead of embedded signature.
It's just a quick hack using the existing module signing mechanism,
thus provided only as a proof of concept for now.

To be noted, it doesn't support the firmwares via udev but only the
direct loading, and the check for built-in firmware is missing, too.
