While this happens to be the same on most boards, it is still a
board-specific decision which UART is the debug uart, or if there is one
at all...

So this property should remain in the dts.

Thanks,

Without the chosen node in base dtsi, the device is not booting up.
Can we have an empty chosen node in the base dtsi and the board-specific 
details
updated in the respective dts file. The device boots up with this.

Thanks,
Rohit

I believe this is something to do with bootloader. But still I don't understand
how this matters at all since the bootloader finally parses the "dtb" only.

Is the bootloader picking up correct dtb?
