   The S2 and S804 records are not recognized by my ROM download which
   is looking for the S3 and S705 records.  I'd bet that there are still
   some linker options that I need to provide but so far I haven't determined
   what the problem is.  Any idea what is causing this problem?

Both S2 and S8 are standard S-record types.  S2 is a data record with
a three byte address.  In this case, the address is 0x10000.  S8 is a
termination record with a three byte address (the 04 you mention is
simply the length of the record, as with all S-record types).  In this
case, the address, which for all termination records (S7/S8/S9) is the
start address of the program, is again 0x10000.

I would recommend fixing your downloader to recognize S1/S2/S8/S9
records, which are perfectly standard.

Otherwise, the linker will generate the smallest type of S-records
that it can get away with.  So, you can force it to generate S3/S7
records by having some section loaded at an address larger than
0xffffff.  Of course, if your board does not have any memory at such
an address, you will probably have other problems during the download.

You can also change the linker behaviour by editing bfd/srec.c.
Search for tdata->type.
