Errors while building USB DWC OTG driver

[Deval Shah]

I followed the libbsd.txt and added bcm 283x driver from freebsd source. Now I am getting new errors. This time drivers got compiled which was verified
using this command. > nm `find build -name '*bcm283x_dwc_fdt*.o'`
The error log is as follows.
In file included from ../../rtemsbsd/rtems/rtems-kernel-muteximpl.c:41:0: 
/home/gadgetman/development/rtems/rtems-libbsd/rtemsbsd/include/machine/rtems-bsd-muteximpl.h:69:5:

The log is very big and it is showing that many structures are missing. I am
unable to figure out why this happened. Because I didn't edit any file related
to rtems-bsd. Any pointers ? Commit for above code changes.

from

nm `find build -name '*bcm283x_dwc_fdt*.o`

the this is the first issue you have to resolve. Read the man
pages of nm and find to figure out what these commands do.

You must have object files for all your driver modules.


I understood the problem. Driver for bcm283x is no getting built. Is there any
documentation availible for porting a driver to rtems-libbsd ? So that I can
verify necessary steps for the code I cherry-picked or if required do the
process from scratch.

See "How to import code from FreeBSD" in libbsd.txt. Great ! Thanks a lot. Please improve the documentation while you work on this. Surely I will.
