For accesses to rom blob data before or during reset, we have a function rom_ptr() which looks for a rom blob that would be loaded to the specified address, and returns a pointer into the rom blob data corresponding to that address. This allows board or CPU code to say "what is the data that is going to be loaded to this address?". However, this function does not take account of memory region aliases. If for instance a machine model has RAM at address 0x0000_0000 which is aliased to also appear at 0x1000_0000, a rom_ptr() query for address 0x0000_0000 will only return a match if the guest image provided by the user was loaded at 0x0000_0000 and not if it was loaded at 0x1000_0000, even though they are the same RAM and a run-time guest CPU read of 0x0000_0000 will read the data loaded to 0x1000_0000. Provide a new function rom_ptr_for_as() which takes an AddressSpace argument, so that it can check whether the MemoryRegion corresponding to the address is also mapped anywhere else in the AddressSpace and look for rom blobs that loaded to that alias.
