At least KuroBox Classic and HG seem to have buggy UART, for which
ETXRDY interrupts are sometimes (once per a few hours?) lost; TX stalls
until next RX arrives.

Since interrupt-based I/O works just fine for other devices, I believe
this problem is due to UART and not to PIC or its driver.

In order to work around this bug, enable COM_HW_BROKEN_ETXRDY bit, as
well as carry out polling once per 10 sec or 1k tics (arbitrary, but
1 min seems too long).

XXX
Apply this for other MPC824x-based boards?

Switch to intr_establish_xname().

Call com_init_regs() in eumbcnattach() to set up com port register mapping.
Fixes broken console output after changes to remove COM_REGMAP.

Sync with HEAD, resolve a few conflicts

Clean up initialization of com_regs structure, in preparation for
some additional changers.

merge to -current.

Replaced 16 by I8259_ICU in intr_establish().

#include <sys/bus.h> instead of <machine/bus.h>.

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.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

- fix description errors in SANDPOINT conf.
- add com and ociic EUMB devices. The latter is under development.

file com_eumb.c was initially added on branch ppcoea-renovation.
