[PATCH 0/8] qemu: arm64: Add support for uefi firmware management protocol routines

[Sughosh Ganu]

This series is based on the capsule update series sent by Takahiro
Akashi[1].

These routines have been tested on the qemu arm64 platform for
updating the u-boot firmware through the capsule-on-disk functionality
of the uefi spec. This series supports updating the u-boot binary
image on platforms booting from arm trusted firmware(tf-a), where the
u-boot image gets booted as the BL33 payload. Support has also been
added for authenticating the capsule file using the public key
contained in the root certificate stored as an efi variable.

The capsule file is placed on the efi system partition(esp), under the
EFI/UpdateCapsule directory. The BootNext and BootXXXX variables are
set accordingly by using the 'efidebug boot add' command. More details
added as part of the documentation patch.
