-/*++
-
-Routine Description:
-
- This routine is called to see if there are any capsules we need to process.
- If the boot mode is not UPDATE, then we do nothing. Otherwise find the
- capsule HOBS and produce firmware volumes for them via the DXE service.
- Then call the dispatcher to dispatch drivers from them. Finally, check
- the status of the updates.
-
-Arguments:
-
- BootMode - the current boot mode
-
-Returns:
-
- EFI_INVALID_PARAMETER - boot mode is not correct for an update
-
-Note:
-
- This function should be called by BDS in case we need to do some
- sort of processing even if there is no capsule to process. We
- need to do this if an earlier update went awry and we need to
- clear the capsule variable so on the next reset PEI does not see it and
- think there is a capsule available.
