 1.12  08-Dec-2018  thorpej Clean up initialization of com_regs structure, in preparation for
some additional changers.
 1.11  01-Jul-2011  dyoung branches: 1.11.52; 1.11.54;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.10  28-Apr-2010  kiyohara Clean up gt and peripherals.
This change tested compile only.
 1.9  21-Nov-2009  rmind branches: 1.9.2; 1.9.4;
Use lwp_getpcb() on mips, powerpc and sh3, clean from struct user usage.
 1.8  28-Apr-2008  martin Remove clause 3 and 4 from TNF licenses
 1.7  14-Mar-2008  cube branches: 1.7.2; 1.7.4;
Split device_t and softc for all com(4) devices (well, everything that
uses a com_softc backend). Use proper types and ansify where appropriate.
 1.6  13-Jul-2006  gdamore branches: 1.6.34; 1.6.54; 1.6.58;
Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Approved by core@. Fixes PR port-evbmips/32362.
