From 8d99026f06978ddf2ed72ccaed6cd3ad0887e4e5 Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Mon, 30 Nov 2020 18:12:11 +0900 Subject: efi_loader: capsule: support firmware update A capsule tagged with the guid, EFI_FIRMWARE_MANAGEMENT_CAPSULE_ID_GUID, is handled as a firmware update object. What efi_update_capsule() basically does is to load any firmware management protocol (or fmp) drivers contained in a capsule, find out an appropriate fmp driver and then invoke its set_image() interface against each binary in a capsule. In this commit, however, loading drivers is not supported. The result of applying a capsule is set to be stored in "CapsuleXXXX" variable, but its implementation is deferred to a fmp driver.
