it is possible to use the beagleboneblack with the 8250 serial
driver or with the deprecated omap serial driver.

Unfortunately serial console get different names (ttyS0 with
8250 driver and ttyO0 with omap driver)

So set SERIAL_CONSOLES to
SERIAL_CONSOLES ?= "115200;ttyS0 115200;ttyO0"

(intentionally with "?=" so it is overwriteable)
and activate

SERIAL_CONSOLES_CHECK = "${SERIAL_CONSOLES}"

with that on the first boot the correct value is picked up
automatically.
