Routine Description:
This parses the FV looking for SEC and patches that address into the
beginning of the FV header.
For LoongArch ISA, the reset vector is at 0x1c000000.
We relocate it to SecCoreEntry and copy the ResetVector code to the
beginning of the FV.
Arguments:
FvImage Memory file for the FV memory image
FvInfo Information read from INF file.
Returns:
EFI_SUCCESS Function Completed successfully.
EFI_ABORTED Error encountered.
EFI_INVALID_PARAMETER A required parameter was NULL.
EFI_NOT_FOUND PEI Core file not found.
