  23         S-Record handling
  24
  25 DESCRIPTION
  26
  27         Ordinary S-Records cannot hold anything but addresses and
  28         data, so that's all that we implement.
  29
  30         The only interesting thing is that S-Records may come out of
  31         order and there is no header, so an initial scan is required
  32         to discover the minimum and maximum addresses used to create
  33         the vma and size of the only section we create.  We
  34         arbitrarily call this section ".text".
  35
  36         When bfd_get_section_contents is called the file is read
  37         again, and this time the data is placed into a bfd_alloc'd
  38         area.
  39
  40         Any number of sections may be created for output, we save them
  41         up and output them when it's time to close the bfd.
  42
  43         An s record looks like:
  44
  45 EXAMPLE
  46         S<type><length><address><data><checksum>
  47
  48 DESCRIPTION
  49         Where
  50         o length
  51         is the number of bytes following upto the checksum. Note that
  52         this is not the number of chars following, since it takes two
  53         chars to represent a byte.
  54         o type
  55         is one of:
  56         0) header record
  57         1) two byte address data record
  58         2) three byte address data record
  59         3) four byte address data record
  60         7) four byte address termination record
  61         8) three byte address termination record
  62         9) two byte address termination record
  63
  64         o address
  65         is the start address of the data following, or in the case of
  66         a termination record, the start address of the image
  67         o data
  68         is the data.
  69         o checksum
  70         is the sum of all the raw byte data in the record, from the length
  71         upwards, modulo 256 and subtracted from 255.
  72

  74 SUBSECTION
  75         Symbol S-Record handling
  76
  77 DESCRIPTION
  78         Some ICE equipment understands an addition to the standard
  79         S-Record format; symbols and their addresses can be sent
  80         before the data.
  81
  82         The format of this is:
  83         ($$ <modulename>
  84                 (<space> <symbol> <address>)*)
  85         $$
  86
  87         so a short symbol table could look like:
  88
  89 EXAMPLE
  90         $$ flash.x
  91         $$ flash.c
  92           _port6 $0
  93           _delay $4
  94           _start $14
  95           _etext $8036
  96           _edata $8036
  97           _end $8036
  98         $$
  99
 100 DESCRIPTION
 101         We allow symbols to be anywhere in the data stream - the module names
 102         are always ignored.
