28 Ordinary S-Records cannot hold anything but addresses and
29 data, so that's all that we implement.
31 The only interesting thing is that S-Records may come out of
32 order and there is no header, so an initial scan is required
33 to discover the minimum and maximum addresses used to create
34 the vma and size of the only section we create. We
35 arbitrarily call this section ".text".
37 When bfd_get_section_contents is called the file is read
38 again, and this time the data is placed into a bfd_alloc'd
41 Any number of sections may be created for output, we save them
42 up and output them when it's time to close the bfd.
44 An s record looks like:
47 S<type><length><address><data><checksum>
52 is the number of bytes following upto the checksum. Note that
53 this is not the number of chars following, since it takes two
54 chars to represent a byte.
58 1) two byte address data record
59 2) three byte address data record
60 3) four byte address data record
61 7) four byte address termination record
62 8) three byte address termination record
63 9) two byte address termination record
66 is the start address of the data following, or in the case of
67 a termination record, the start address of the image
71 is the sum of all the raw byte data in the record, from the length
72 upwards, modulo 256 and subtracted from 255.
75 Symbol S-Record handling
78 Some ICE equipment understands an addition to the standard
79 S-Record format; symbols and their addresses can be sent
82 The format of this is:
84 (<space> <symbol> <address>)*)
87 so a short symbol table could look like:
101 We allow symbols to be anywhere in the data stream - the module names
102 are always ignored. */
