Porting ethernet driver from FREEBSD to rtems-libbsd

[ragu nath]

Hi All,

My name is ragunath. I am selected for Google Summer of Code 2015 with
RTEMS. I will be working on improving Beagle BSP.

I am in the process of porting ethernet driver for Beaglebone black
from FreeBSD to rtems-libbsd.  I would like to know what are the
necessary changes we need to make to add a driver. BBB is based on ARM
Am335x SoC.

What are the bsp specific changes we need to do (bus support api's,
interrupt support, etc)? I understand all the devices are under nexus
device in rtems-libbsd. In the FreeBSD code, it is under simplebus.
What are the changes we need to do to take care of this?

If there is any documentation available on this topic pls let me know.


Thanks,
Ragunath
