Cameras are complex devices that need heavy hardware image processing
operations. Control of the processing is based on advanced algorithms
that must run on a programmable processor. This has traditionally been
implemented in a dedicated MCU in the camera, but in embedded devices
algorithms have been moved to the main CPU to save cost. Blurring the
boundary between camera devices and Linux often left the user with no
other option than a vendor-specific closed-source solution.

To address this problem the Linux media community has very recently
started collaboration with the industry to develop a camera stack that
will be open-source-friendly while still protecting vendor core IP.
libcamera was born out of that collaboration and will offer modern
camera support to Linux-based systems, including traditional Linux
distributions, ChromeOS and Android.

The project has not made an official release as of yet, so we're
using the latest sha1 from master

We utilise C++ 11 but we mandate GCC5+ due to a bug [0] in earlier
versions which result in compile failures on our code base.

[0] Bug 54316 - [C++11] move constructor for stringstream
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54316

Documentation and Tests are disabled from the build.

With the following added to libcamera.config:

  BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
  BR2_PACKAGE_LIBCAMERA=y

./utils/test-pkg -c libcamera.config -p libcamera
                             br-arm-full [1/6]: SKIPPED
                  br-arm-cortex-a9-glibc [2/6]: OK
                   br-arm-cortex-m4-full [3/6]: SKIPPED
                          br-x86-64-musl [4/6]: OK
                      br-arm-full-static [5/6]: SKIPPED
                            sourcery-arm [6/6]: SKIPPED

Hi All...

I'm sorry - a debug line has crept in that I thought I had kept out of
the patch.

V2 (actually it's V3 anyway) to arrive imminently....

Sorry for the noise.
