what - beside making the hardware - has to be done in principle to add an external audio codec to BeagleBone board (OMAPAM3358 based, with I2S but without a codec on board)?

I'm not really familiar with BeagleBone, and AM3359, but: You will need a driver for McASP (0 is routed to expansion). It looks like that the McASP IP is the same as in DaVinci. With luck you might be able to reuse the code for AM3359. Apart from this you will need a machine driver.
