Module Name:    src
Committed By:   martin
Date:           Thu Jul 16 12:39:11 UTC 2020

Modified Files:
        src/sys/dev/pci [netbsd-9]: piixpm.c piixpmreg.h

Log Message:
Pull up the following revisions, requested by msaitoh in ticket #1017:

        sys/dev/pci/piixpm.c                    1.57-1.59, 1.61-1.63 via patch
        sys/dev/pci/piixpmreg.h                 1.9-1.12

- Fix number of port for Hudson rev. 0x1f and newer.
- Read SB800_SMB_HOSTC correctly. This register is not in the PCI
  config space but in the I/O space.
- The bit 0 of SB800_SMB_HOSTC is 0 on SMI and 1 on IRQ, so invert the
  check.
- Don't force using SMBUS0SEL register.
- Acquire/release host semaphore to share SMBus between the host and
  the embedded controller (IMC). Without this change, "shutdown -r"
  does power off and not boot on some machines.
- Save/restore port number before selecting port.
- Modify comment.
- Whitespace fix.
