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.
