+/* SUBSECTION
+ S-Record handling
+
+ DESCRIPTION
+
+ Ordinary S-Records cannot hold anything but addresses and
+ data, so that's all that we implement.
+
+ The only interesting thing is that S-Records may come out of
+ order and there is no header, so an initial scan is required
+ to discover the minimum and maximum addresses used to create
+ the vma and size of the only section we create. We
+ arbitrarily call this section ".text".
+
+ When bfd_get_section_contents is called the file is read
+ again, and this time the data is placed into a bfd_alloc'd
+ area.
+
+ Any number of sections may be created for output, we save them
+ up and output them when it's time to close the bfd.
+
+ An s record looks like:
+
+ EXAMPLE
+ S<type><length><address><data><checksum>
+
+ DESCRIPTION
+ Where
+ o length
+ is the number of bytes following upto the checksum. Note that
+ this is not the number of chars following, since it takes two
+ chars to represent a byte.
+ o type
+ is one of:
+ 0) header record
+ 1) two byte address data record
+ 2) three byte address data record
+ 3) four byte address data record
+ 7) four byte address termination record
+ 8) three byte address termination record
+ 9) two byte address termination record
+
+ o address
+ is the start address of the data following, or in the case of
+ a termination record, the start address of the image
+ o data
+ is the data.
+ o checksum
+ is the sum of all the raw byte data in the record, from the length
+ upwards, modulo 256 and subtracted from 255.
+
+ SUBSECTION
+ Symbol S-Record handling
+
+ DESCRIPTION
+ Some ICE equipment understands an addition to the standard
+ S-Record format; symbols and their addresses can be sent
+ before the data.
+
+ The format of this is:
+ ($$ <modulename>
+ (<space> <symbol> <address>)*)
+ $$
+
+ so a short symbol table could look like:
+
+ EXAMPLE
+ $$ flash.x
+ $$ flash.c
+ _port6 $0
+ _delay $4
+ _start $14
+ _etext $8036
+ _edata $8036
+ _end $8036
+ $$
+
+ DESCRIPTION
+ We allow symbols to be anywhere in the data stream - the module names
+ are always ignored. */
