At least in the case of DRA7 boards, they are not written specifically since they come out over onboard FTDI usb2serial. This will at least ensure that /dev/ttyO9 will always point to uart10 no matter the board, instead of having ttyO0 always pointing to console serial port no matter the board (and having to guess which figure out it actually was aliased to). -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
