[PATCH 0/4] firmware: signature verification

[AKASHI Takahiro]

This is my first version of patch series for adding signature
verification to firmware loading.

The original idea and code came from the work by Luis some time ago,
and I migrated it with some improvements to new driver data APIs,
leaving request_firmware() intact.

For details about how it works, please see the commit message of
patch#1 and the document under Documentation/driver-api/firmware.

Please note that patch#3, test script, is still a bit rough-edged,
especially that we have to prepare some data files in advance.
I will try to improve it for better automation.

For you convenience, the patch is available:
