The debug message will be displayed only when FSP API returned error status, and when Boot Loader called the subsequent FSP API again. The idea here is to return the control back to Boot Loader if there is any error in the previous API Call, without proceeding further and not having a hang inside the FSP.
Note: Regular FSP API call status will be displayed in debug message, before returning the control back to the Boot Loader.

Subject: RE: [PATCH] IntelFsp2Pkg: Support to return error status from FSP API done
Hi Richard,
In the below snippet the debug message is based on the API status and will not be display if the switch stack already happened right? Also since it is in a do while loop "cannot proceed further" is not necessarily accurate.

Thanks,
