Subject: efidebug: capsule: Add a command to update capsule on disk
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=7407595286f81d18eb14a9c4d8d90bdd159d6a5c;p=u-boot.git

efidebug: capsule: Add a command to update capsule on disk

Add a efidebug subcommand to initiate a firmware update using the efi
firmware management protocol(fmp) set_image routine.

The firmware update can be initiated through

'efidebug capsule disk-update'

This would locate the efi capsule file on the efi system partition,
and call the platform's set_image fmp routine to initiate the firmware
update.
