## PCI Serial Device Info. It is an array of Device, Function, and Power Management
# information that describes the path that contains zero or more PCI to PCI briges
# followed by a PCI serial device. Each array entry is 4-bytes in length. The
# first byte is the PCI Device Number, then second byte is the PCI Function Number,
# and the last two bytes are the offset to the PCI power management capabilities
# register used to manage the D0-D3 states. If a PCI power management capabilities
# register is not present, then the last two bytes in the offset is set to 0. The
# array is terminated by an array entry with a PCI Device Number of 0xFF. For a
# non-PCI fixed address serial device, such as an ISA serial device, the value is 0xFF.
