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.
Signed-off-by: Heiko Schocher hs@denx.de cc: Michael Zaidman michael.zaidman@gmail.com --- maybe I should include genutils.h in common.h ?
