Hi

I figured out that there were some unnecessary imports I was doing and also
some necessary
header files that I'm missing, after adding those most of the warnings
vanished. The error I'm
seeing now is due to a missing '.m' header file. The error looks like this
...
=========
   ../../freebsd/sys/arm/ti/am335x/tda19988.c:56:10: fatal error:
rtems/bsd/local/iicbus_if.h: No such file or directory
 #include <rtems/bsd/local/iicbus_if.h>
=========
There's an iicbus_if.m file in the freebsd source which is being included as
``#include "iicbus_if.h"``
How to work with the .m files ?

Thanks
