[U-Boot] [PATCH 1/2] common: introduce a genutils.h file

[Heiko Schocher]

as discussed in thread
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/76654

and as a result of this discussion Michael Zaidman
proposed to create a genutils.h, see:

http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/78692

So, introduce this genutils.h, as BUILD_BUG_ON is also
needed in sensor support.

maybe I should include genutils.h in common.h ?
