Basically, I have no objection to add stdout-path property on board DT but I
need to ask other ARM guys how they think about? Always I'm questioned what
should be defined in bootloader before entering kernel and IMHO kernel can do
it, it should be defined in bootloader though ;)

Let's wait for other opinions...

Thanks,
Kukjin
