REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1525 The patch is to merge multiple FMP instances into single ESRT entry when they have the same GUID. The policy to LastAttemptStatus/LastAttemptVersion of ESRT entry is: If all the LastAttemptStatus are LAST_ATTEMPT_STATUS_SUCCESS, then LastAttemptVersion should be the smallest of LastAttemptVersion. If any of the LastAttemptStatus is not LAST_ATTEMPT_STATUS_SUCCESS, then the LastAttemptVersion/LastAttemptStatus should be the values of the first FMP instance whose LastAttemptStatus is not LAST_ATTEMPT_STATUS_SUCCESS. To detect possible duplicated GUID/HardwareInstance, a table of GUID/HardwareInstance pairs from all the EFI_FIRMWARE_IMAGE_DESCRIPTORs from all FMP instances is built. If a duplicate is found, then generate a DEBUG_ERROR message, generate an ASSERT(), and ignore the duplicate EFI_FIRMWARE_IMAGE_DESCRIPTOR. Add an internal worker function called FmpGetFirmwareImageDescriptor() that retrieves the list of EFI_FIRMWARE_IMAGE_DESCRIPTORs from a single FMP instance and returns the descriptors in an allocated buffer. This function is used to get the descriptors used to build the table of unique GUID/HardwareInstance pairs. It is then used again to generate the ESRT Table from all the EFI_FIRMWARE_IMAGE_DESCRIPTORs from all the FMP instances. 2 passes are performed so the total number of descriptors is known. This allows the correct sized buffers to always be allocated.
