Status of BeagleBone Black UARTs

[Winston Smith]

I found an email thread from last year discussing enabling the BBB's
additional UARTs:

http://freebsd.1045724.n5.nabble.com/Beaglebone-Serial-Ports-Progress-td5787251.html

Has there been any update on this?  Do I still need to use Ian [Young]'s patch?

I do see in the bboneblk.dts that all 5 uarts are listed, however
dmesg only mentions uart0 and I don't see any additional tty devices
in /dev.

Thanks!
