[PATCH v4 0/2] Support EFI capsule updates across Amlogic boards

[Ferass El Hafidi]

Currently EFI capsule updates are only supported on the following
Amlogic-based boards:

 - Libre Computer AML-S805X-AC
 - Libre Computer AML-A311D-CC
 - Libre Computer AML-S905D3-CC

This is done with board-specific configuration in board/libre-computer/.

With this patch, EFI capsule updates can now work on most of the other
Amlogic boards supported by u-boot, such as the Libre Computer
AML-S905X-CC, without the need for board-specific configuration
beforehand.

Please note that flashing to the eMMC bootX partitions is not yet
supported.

(Also: with these patches, the Libre Computer boards are switched to use
the new common EFI capsule support. This will mean GUIDs will change, as
fw_image name is different.)
