Hi all,

This is my next attempt to get around the ACPI resource conflict on p3b-f:

https://review.coreboot.org/c/coreboot/+/41735

Done up to the SCMI spec here:
http://smbus.org/specs/smbus_cmi10.pdf

The standard device _HID should have been SMBUS01, but our iasl will
not accept that, insisting the last 4 letters be hex digits.

I left off _SBT and _SBA because the hardware doesn't do alerts and
the only device doing block transfers is the clock chip, which is not
accessible without further tricks.

If I call the methods directly, they seem to work. But Linux 4.4.14
isn't picking up the device. Manually load the driver and I still
don't get the PIIX4 SMBus. Also it doesn't seem to write properly - I
could no longer get my message and power LEDs to blink after this
upgrade.

Can you see any faults in my work just by looking at it?

Thanks
Keith
