[PATCH v2 0/7] Hexagon Geosystems GS05 Board Support

[Marco Felsch <m.felsch@pengutronix.de>]

Hi,

this series adds the support for the Hexagon Geosystems GS05 product
[1]. The GS05 is part of a larger product family from SW pov, therefore
most logic is implemented below 'common/boards/hgs'.

The board support was added before the new security-profiles made it
into barebox mainline, therefore security-profiles aren't used yet but
maybe in the future.

Further products will be send mainline as well, once this basic support
got merged.

Regards,
  Marco
