+  Passes capsules to the firmware with both virtual and physical mapping. 

+  Depending on the intended consumption, the firmware may

+  process the capsule immediately. If the payload should persist across a

+  system reset, the reset value returned from EFI_QueryCapsuleCapabilities must

+  be passed into ResetSystem() and will cause the capsule to be processed by 

+  the firmware as part of the reset process.

+  

+  @param  CapsuleHeaderArray    Virtual pointer to an array of virtual pointers to the capsules

+                                being passed into update capsule. Each capsules is assumed to

+                                stored in contiguous virtual memory. The capsules in the

+                                CapsuleHeaderArray must be the same capsules as the

+                                ScatterGatherList. The CapsuleHeaderArray must

+                                have the capsules in the same order as the ScatterGatherList.

+  @param  CapsuleCount          Number of pointers to EFI_CAPSULE_HEADER in

+                                CaspuleHeaderArray.

+  @param  ScatterGatherList     Physical pointer to a set of

+                                EFI_CAPSULE_BLOCK_DESCRIPTOR that describes the

+                                location in physical memory of a set of capsules. See Related

+                                passed via this interface. The capsules in the

+                                ScatterGatherList must be in the same order as the

+                                CapsuleHeaderArray. This parameter is only referenced if

+                                the capsules are defined to persist across system reset.

+  @retval EFI_INVALID_PARAMETER CapsuleSize is NULL or ResetTye is NULL.

+  @retval EFI_DEVICE_ERROR      The capsule update was started, but failed due to a device error.

+ 

+  The QueryCapsuleCapabilities() function allows a caller to test to see if a capsule or

+  capsules can be updated via UpdateCapsule(). The Flags values in the capsule header and

+  size of the entire capsule is checked.

+  If the caller needs to query for generic capsule capability a fake EFI_CAPSULE_HEADER can be

+  constructed where CapsuleImageSize is equal to HeaderSize that is equal to sizeof

+  (EFI_CAPSULE_HEADER). To determine reset requirements,

+  CAPSULE_FLAGS_PERSIST_ACROSS_RESET should be set in the Flags field of the

+  EFI_CAPSULE_HEADER.

+  The firmware must support any capsule that has the

+  CAPSULE_FLAGS_PERSIST_ACROSS_RESET flag set in EFI_CAPSULE_HEADER. The

+  firmware sets the policy for what capsules are supported that do not have the

+  CAPSULE_FLAGS_PERSIST_ACROSS_RESET flag set.
