Merge tag 'docs-4.13' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet:
 "There has been a fair amount of activity in the docs tree this time
  around. Highlights include:

   - Conversion of a bunch of security documentation into RST

   - The conversion of the remaining DocBook templates by The Amazing
     Mauro Machine. We can now drop the entire DocBook build chain.

   - The usual collection of fixes and minor updates"

<title>Introduction</title>
<para>
The generic Reed-Solomon Library provides encoding, decoding
and error correction functions.
</para>
<para>
Reed-Solomon codes are used in communication and storage
applications to ensure data integrity.

the functions provided by the library.

<title>Usage</title>
<para>
This chapter provides examples of how to use the library.
</para>
<sect1>
<title>Initializing</title>
<para>
The init function init_rs returns a pointer to an
rs decoder structure, which holds the necessary
information for encoding, decoding and error correction
with the given polynomial. It either uses an existing
matching decoder or creates a new one. On creation all
the lookup tables for fast en/decoding are created.
The function may take a while, so make sure not to
call it in critical code paths.
</para>
<programlisting>
/* the Reed Solomon control structure */
static struct rs_control *rs_decoder;
/* Symbolsize is 10 (bits)
* Primitive polynomial is x^10+x^3+1
* first consecutive root is 0
* primitive element to generate roots = 1
* generator polynomial degree (number of roots) = 6
*/
rs_decoder = init_rs (10, 0x409, 0, 1, 6);
</programlisting>
</sect1>
<sect1>
<title>Encoding</title>
<para>
The encoder calculates the Reed-Solomon code over
the given data length and stores the result in
the parity buffer. Note that the parity buffer must
be initialized before calling the encoder.
</para>
<para>
The expanded data can be inverted on the fly by
providing a non-zero inversion mask. The expanded data is
XOR'ed with the mask. This is used e.g. for FLASH
ECC, where the all 0xFF is inverted to an all 0x00.
The Reed-Solomon code for all 0x00 is all 0x00. The
code is inverted before storing to FLASH so it is 0xFF
too. This prevents that reading from an erased FLASH
results in ECC errors.
</para>
<para>
The databytes are expanded to the given symbol size
on the fly. There is no support for encoding continuous
bitstreams with a symbol size != 8 at the moment. If
it is necessary it should be not a big deal to implement
such functionality.
</para>
<programlisting>
/* Parity buffer. Size = number of roots */
uint16_t par[6];
/* Initialize the parity buffer */
memset(par, 0, sizeof(par));
/* Encode 512 byte in data8. Store parity in buffer par */
encode_rs8 (rs_decoder, data8, 512, par, 0);
</programlisting>
</sect1>
<sect1>
<title>Decoding</title>
<para>
The decoder calculates the syndrome over
the given data length and the received parity symbols
and corrects errors in the data.
</para>
<para>
If a syndrome is available from a hardware decoder
then the syndrome calculation is skipped.
</para>
<para>
The correction of the data buffer can be suppressed
by providing a correction pattern buffer and an error
location buffer to the decoder. The decoder stores the
calculated error location and the correction bitmask
in the given buffers. This is useful for hardware
decoders which use a weird bit ordering scheme.
</para>
<para>
The databytes are expanded to the given symbol size
on the fly. There is no support for decoding continuous
bitstreams with a symbolsize != 8 at the moment. If
it is necessary it should be not a big deal to implement
such functionality.

<para>
RapidIO is a high speed switched fabric interconnect with
features aimed at the embedded market. RapidIO provides
support for memory-mapped I/O as well as message-based
transactions over the switched fabric network. RapidIO has
a standardized discovery mechanism not unlike the PCI bus
standard that allows simple detection of devices in a
network.

<para>
This documentation is provided for developers intending
to support RapidIO on new architectures, write new drivers,
or to understand the subsystem internals.

Drivers are provided a set of calls in order
to interface with the subsystem to gather info
on devices, request/map memory region resources,
and manage mailboxes/doorbells.
