No, quite the contrary. In Linux you will find even the cpu-specific drivers
(like ethernet, uart, i2c driver etc) in the "drivers" directory. Only the
board- and cpu-specific setup code and some additional code like interrupt
controller implementation etc is normally found in the Linux "arch"
This is one of the reason for me to suggest this.

No it doesn't.

I still think we should move to implementing drivers in the drivers directory,
even if the responsibility for the files is not so easily visible anymore.
