I wonder if adding this drivers to libbsd is itself a meaty task. Do we need a ticket for this ? Also, the driver uses i2c bus driver from FreeBSD source, I see that the i2c driver is nicely supported in the rtems beagle bsp, how to use the i2c module in the bsp, with the hdmi framer driver in libbsd ?
