/**

|
|
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.
|
|
|
|
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 away 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.
|
|
|
|
@param BootMode the current boot mode
|
|
|
|
@retval EFI_INVALID_PARAMETER boot mode is not correct for an update
|
|
@retval EFI_SUCCESS There is no error when processing capsule
