#define ASSERT_INVALID_PCI_SEGMENT_ADDRESS ( A,
 )     ASSERT (((A) & (0xffff0000f0000000ULL | (M))) == 0)

Assert the validity of a PCI Segment address. A valid PCI Segment address should not contain 1's in bits 28..31 and 48..63

Parameters:
A The address to validate.
M Additional bits to assert to be zero.

#define PCI_TO_PCI_ROOT_BRIDGE_IO_ADDRESS (  )     ((((UINT32)(A) << 4) & 0xff000000) | (((UINT32)(A) >> 4) & 0x00000700) | (((UINT32)(A) << 1) & 0x001f0000) | (LShiftU64((A) & 0xfff, 32)))

Translate PCI Lib address into format of PCI Root Bridge I/O Protocol

Parameters:
A The address that encodes the PCI Bus, Device, Function and Register.
