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.
