Merge lp:~salgado/linaro-image-tools/config-class into lp:linaro-image-tools/11.11

[Guilherme Salgado]

Store board config in python classes. This will make it possible for us to
move the board-specific out of populate_boot.py and into boards.py, where all
board-specific stuff will live.

[James Westby (james-w)]

Looks good to me.

Thanks,

James
