Hi Linus

You can append the baud rate etc to uart0, and then don't need
bootargs.

include/dt-bindings/input/linux-event-codes.h and then

	                linux,code = <KEY_EJECTCD>

The convention is that the first part of the label is the machine
name. OpenWRT and others often does something else... So

s/status/pogoplugv4/g

Is there something on this i2c bus?

Thanks
