https://review.coreboot.org/#/c/coreboot/+/26287/ is already included. I
see "ACPI: * H8" and have the following mentions of HBDC inside the
External (HBDC, IntObj)
Method (GBDC, 0, NotSerialized)
Local0 = One
Local0 |= 0x02
Local0 |= 0x04
Method (SBDC, 1, NotSerialized)
Local0 = ((Arg0 & 0x02) >> One)
