[PATCH 0/4] EFI capsule update support

From: Matt Fleming
Date: Thu Mar 17 2016 - 08:57:20 EST

This is the reincarnation of the EFI capsule patches I originally
posted in 2013, plus Hock's capsule loader driver from earlier this
year. Together they provide a way for users to send capsule images to

EFI capsules are binary blobs passed from the OS to the firmware. The
firmware then parses them and makes some decision based upon their
contents. The most common use case is to bundle a flashable firmware
image into a capsule that the firmware can use to upgrade the existing
version in the flash.

The series has been tested on the Intel Quark Galileo.

I plan on queuing this up for v4.7.
