Macro that converts PCI Bus, PCI Device, PCI Function and PCI Register to an address that can be passed to the PCI Library functions.
Computes an address that is compatible with the PCI Library functions. The unused upper bits of Bus, Device, Function and Register are stripped prior to the generation of the address.

Device | PCI Device number. Range 0..31. | |
Function | PCI Function number. Range 0..7. | |

Writes the 8-bit PCI configuration register specified by Address with the value specified by Value. Value is returned. This function must guarantee that all PCI read and write operations are serialized.
If Address > 0x0FFFFFFF, then ASSERT().

Copies the data in a caller supplied buffer to a specified range of PCI configuration space.
Writes the range of PCI configuration registers specified by StartAddress and Size from the buffer specified by Buffer. This function only allows the PCI configuration registers from a single PCI function to be written. Size is returned. When possible 32-bit PCI configuration write cycles are used to write from StartAdress to StartAddress + Size. Due to alignment restrictions, 8-bit and 16-bit PCI configuration write cycles may be used at the beginning and the end of the range.
If StartAddress > 0x0FFFFFFF, then ASSERT(). If ((StartAddress & 0xFFF) + Size) > 0x1000, then ASSERT(). If Size > 0 and Buffer is NULL, then ASSERT().
