[PATCH v3 0/3] Add support for multiple required keys

[Thirupathaiah Annapureddy]

This patch series adds the support for multiple required keys
in U-Boot DTB with test support.

Changes in v3:
- Replaced 'u-boot' with 'U-Boot' in commit messages.
- Added an explicit print message to indicate that no required signature
was verified.

Changes in v2 (thanks for the feedback Simon and Rasmus):
- Introduce a policy variable in U-boot DTB to control whether any or all
required keys must have signed configuration.
- Added tests to cover any or all required keys policy. 
- Updated signature.txt to include required-mode policy information.

  vboot: add DTB policy for supporting multiple required conf keys
  test: vboot: add tests for multiple required keys
