Hi Michael,
I guess I might not understand the exact use cases for the enum. It seems like the meaning of the error codes you only want to be known within FmpDevicePkg, but it appears to me that the error code values could traverse to drivers outside this package, is that correct?
Thanks,
Nate

Subject: Re: [edk2-devel] [PATCH v2 2/6] FmpDevicePkg: Add LastAttemptStatus.h
I realized there is room for misinterpretation of the macros LAST_ATTEMPT_STATUS_DRIVER_ERROR_COUNT and LAST_ATTEMPT_STATUS_DEPENDENCY_ERROR_COUNT based on name.
If there's no further feedback on the topic, I'll change them to LAST_ATTEMPT_STATUS_DRIVER_ERROR_RANGE_LENGTH and LAST_ATTEMPT_STATUS_DEPENDENCY_ERROR_RANGE_LENGTH.
Thanks,
Michael
