Re: [PATCH v2 00/10] ARM: boards: add support for Enclustra Mercury SA2

[Sascha Hauer <s.hauer@pengutronix.de>]

Hi David,

Please squash patches 2, 3, 4, 5, 6, 7 and 10 into one patch.
It's easier to review the end result rather than development steps.
The handoff files should stay a separate commit though because they are
quite big and only contain autogenerated stuff.

Sascha
