Why "=y" here?  Shouldn't this just read:
	depends on SERIAL_AMBA_PL011?

quoted

+	select SERIAL_CORE

Is this needed?  SERIAL_AMBA_PL011 already selects this.

I am not sure. I found this few lines above:

config SERIAL_AMBA_PL010_CONSOLE
	bool "Support for console on AMBA serial port"
	depends on SERIAL_AMBA_PL010=y
	select SERIAL_CORE_CONSOLE

and modified it for my purpose.


Thanks,

Ivan
