These registers are initialized with fixed reset values or with values stored in the I²C serial
EEPROM and then used by the PCI HOST, mainly during the Power-On Self Test (POST)
for plug and play functionality or later by the operating system for enumeration.
The PCI Vendor ID equals 0x107E, and the PCI Device ID equals 0x9070.
PowerSpan PCI Registers
These registers are used to define the parameters of the PCI-to-Local windows. They are
mapped in the PCI memory space (base address defined in PCI configuration register 0x14
PCIBAR1) and in the local space for the local processor (base address 0xF0020000).
