Vinicius May f6ecf80ebb Documentation: brand new layout for NuttX documentation.
The documentation grew one page at a time, so the tree follows the
history of who wrote what and not the shape of NuttX. Scheduling is
spread over three places, a driver page can sit above the subsystem
that owns it, and the front page lists everything at the same level.
That is a lot to face when all you want to know is where the scheduler
lives.

This change files every page under the code it describes. It is a move,
not a rewrite: outside the ten pages named below, every page keeps the
text that is already in master, and no page's text is deleted.

What it does:

* Groups the table of contents into nine chapters.
* Moves the OS subsystems under os/: scheduling, memory, drivers,
  filesystem, networking, IPC, interrupts, libs, time.
* Renames the platform pages to the names the source tree uses, and
  derives their tags from the tree instead of by hand.
* Splits guides/ by subject.
* Adds Documentation/redirects.py, with a rule for every page that left
  its old path, so old URLs keep working. The redirect page also carries
  a link's #anchor across to the new page.

Ten pages have text that is new or rewritten. Nine of them are the
landing page of a chapter, which has to exist for the new structure:

    index                  the front page
    os/index               OS Design
    os/scheduling/index    Scheduling
    os/interrupts/index    Interrupts
    os/ipc/index           IPC
    os/time/index          Time and timers
    about/index            About
    developing/index       Developing NuttX
    ReleaseNotes/index     Release notes

The tenth is os/libs/libbuiltin, the only page here with technical
content: libs/libbuiltin/ had no page at all. Five SVG diagrams come
with these pages, hand-written XML with no editor metadata.

Nothing outside Documentation/ is touched.

How it was checked:

* Sphinx builds with -W: no warnings, and no document left outside a
  toctree.
* A script, offered in the PR, proves the narrow claim this rests on.
  For every page outside the ten named above it erases what a move
  touches -- link target, path, tag line, toctree block, table border --
  from the whole old text and the whole new text, and requires the two
  to be byte for byte identical. It also requires every sentence of a
  deleted page to turn up somewhere, and every page that left its old
  path to have a redirect, from a URL that existed, to where its content
  went. It exits non-zero and names the page if any of that is not true,
  and it tests added pages too, so forgetting to declare one cannot make
  it pass.
* An independent audit checked 133 factual claims on these ten pages
  against the tree, one shell command per claim: 130 confirmed, 1
  refuted and fixed here, 2 not checkable.
* tools/checkpatch.sh is clean over the range.

The diff is large because moving a page changes every link that points
to it. Most of it is pure renames, and board pages that gained one tag
line.

NuttX-6.10

The 77th release of NuttX, Version 6.10, was made on October 6, 2011 and is available for download from the SourceForge website. Note that release consists of two tarballs: nuttx-6.10.tar.gz and apps-6.10.tar.gz. Both may be needed (see the top-level nuttx/README.txt file for build information).

This release corresponds with SVN release number: r4028

This release includes a few new features and several important bug fixes. The new features (some still incomplete) include:

  • CDC ACM serial class device-side driver

  • RTC: Now supports hi-res and lo-res hardware RTC. The lo-res RTC runs at 1Hz.

  • STM32 I2C driver. Now supports faster, polled mode of operation. Added an I2C trace capability.

  • ADS7843E touchscreen driver. As used on the SAM3U-EK development board.

  • AT91SAM3U SPI driver. To support the ADS7843E toucscreen

  • X11 Support on simulation target. Build errors in the X11 windows for the simulated target have been correct. Added support for a simulated touchscreen on the X11 window (based on mouse inputs).

  • System Timer. Added support for a 64-bit system timer.

  • TIFF Support. Added a TIFF library (currently used for storing LCD screen shots).

  • LCD Support. Added a test to verify that we read and write correct to LCD GRAM memory.

  • I2C tool. Extended to support to include a verify command and repetitions and auto-address increment for most commands.

  • USB terminal example. Line oriented serial bridge connects a host USB serial terminal to a host UART serial terminal.

  • Build System. apps/ Makefile will now include external directories in the application build.

Bugfixes, order roughly on decreasing criticality include:

  • Message Queues. Correct errors in mq_timedsend() and mq_timedreceive().

  • FAT. Writes that cross sector boundaries, stray write into the FAT, and a FAT long file name issue

  • NXFFS. Added a missed error check. Files cannot be opened for writing if they are already opened for reading.

  • Library: fopen() for append modse was not appending.

  • STM32 I2C driver. Correct another conflict between concurrent FSMC and I2C1 accesses. Fixed some bad error detection logic.

  • STM32 SDHC driver. Interrupts were being left disabled.
