Hi,

This patch series attempts to generalise our BCM2835 ISP statistics structure
with the aim of removing any hardware specific structures, defines and header
files from the algorithm source files.

Patch 1 defines the generalised statistics structures.
Patches 2 and 3 are some simple tidy-ups to prepare for the changes.
Patch 4 converts our algorithms to use the generalised structures.
Patch 5 is another tidy up to remove a platform specific define from the AGC.

Thanks,
Naush
