It isn't a mistake. "serial" is meaningless with you've got multiple
serial ports of different types. It's a general name of a class of
devices, not a specific device.

Well, core.c is the core driver which knows how to talk to user space,
and on to that bolts the hardware specific bits, 8250.c, sa1100.c,
suncore.c etc.

In theory they can, and maybe one day we'll teach the Kconfig system
to allow it. Feel free to send a patch for this. 8)
