I don't know if there's another use case besides flash load that should
definitely use the physical address, so I can't be much help answering that
question. I was mainly relying on tests to catch any issue caused by using
physical addresses.
Could the value_is_offset flag be a tell here? Looks like that load bias is
only calculated if value_is_offset == false. Would it make sense to always use
virtual address in such a case? It wouldn't affect the "target modules load"
case, which always sets value_is_offset to true.
