Commit Message

Peter Griffin Nov. 7, 2014, 11:57 a.m.
The stih410 soc which will be added in the following commit is very similar to
the stih407, to enable maximum re-use of the dt files this commit abstracts the
common parts into a shared dt file stihxxx-b2120 for the board, and also a shared
file stih407-family.dtsi for the SoC.

Please leave these in the per-board file, each board would have different
values, so it makes no sense to have them in the shared file.
