[PATCH v2 00/11] ARM: add support for Canon DIGIC chips and Canon PowerShot A1100 IS

[Antony Pavlov]

Changes since v1:

  * fix reset_cpu();
  * add real Canon A1100 camera support.

DIGIC is Canon Inc.'s name for a family of SoC
for digital cameras and camcorders.

See http://en.wikipedia.org/wiki/DIGIC for details.

There is no publicly available specification for
DIGIC chips. All information about DIGIC chip
internals is based on reverse engineering efforts
made by CHDK (http://chdk.wikia.com) and
Magic Lantern (http://www.magiclantern.fm) projects
contributors.

Also this patch series adds initial support for Canon
PowerShot A1100 IS compact camera (it is my only camera
with connected UART interface). As the DIGIC-based cameras
differences mostly are unsignificant (e.g. RAM-size,
ROM type and size, GPIO usage) the other compact
and DSLR cameras support can be easely added.

One can easely run barebox for Canon A1100 using QEMU version 2.0
or newer.

This patchseries uses some patches already submitted to maillist:

   * clean barebox.zynq
   * treewide: drop Doxygen stuff
