PS2, Line 14: Ideally FSP API should be able to return the status (both success and
            : error code) upon exiting the FSP API but unfortunately there are some
            : scenarios in ADL/RPL FSP where MultiPhaseSiInit API is unable to return
            : any ERROR status. Hence, this function provides an additional hook to
            : read the FSP reset status by reading the dedicated HOB without relying
            : on the FSP API exit status code.
> Is there an FSP upstream bug report for this? If yes, it’d be great if you referenced it.

the bug being mentioned in the commit msg is the own assigned to Intel and there will be external communication from Intel
