   2   Capsule Architectural Protocol as defined in PI1.0a Specification VOLUME 2 DXE
   3
   4   The DXE Driver that produces this protocol must be a runtime driver.
   5   The driver is responsible for initializing the CapsuleUpdate() and
   6   QueryCapsuleCapabilities() fields of the UEFI Runtime Services Table.
   7   After the two fields of the UEFI Runtime Services Table have been initialized,
   8   the driver must install the EFI_CAPSULE_ARCH_PROTOCOL_GUID on a new handle
   9   with a NULL interface pointer. The installation of this protocol informs
  10   the DXE Foundation that the Capsule related services are now available and
  11   that the DXE Foundation must update the 32-bit CRC of the UEFI Runtime Services Table.
