[Buildroot] can't open /dev/ttyO2: No such file or directory

[Belisko Marek]

Hi,

this is not mainly related to BR bt maybe somebody facing same problems.
I have rootfs builded by BR (just busybox with external toolchain for
Cortex-A9).
I'm booting kernel 3.7-rc1 on pandaboard with devicetree on barebox.
Booting seems to be
fine till point when IMO getty is started. Then I get console full of :
can't open /dev/ttyO2: No such file or directory
