Subject: board: sk-am69: Define capsule update firmware info
X-Git-Url: http://git.dujemihanovic.xyz/img/static/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=a4d5e5daa8476469d9d990d4bfc5bf2627dc7b00;p=u-boot.git

board: sk-am69: Define capsule update firmware info

Define the firmware components updatable via EFI capsule update, including
defining capsule GUIDs for the various firmware components for the AM69
SK.

TODO: possibly make the struct's sk specific.
TODO: add doc commit (and make sure doc is sk/NOR specific, and add OSIP
boot mode)
TODO: update doc to show sk defconfig when building
