EFI_PEI_ISA_HC_CLOSE_IO | CloseIoAperture |
The address of the ISA/LPC Bridge device. For PCI, this is the segment, bus, device and function of the a ISA/LPC Bridge device.
If bits 24-31 are 0, then the definition is: Bits 0:2 - Function Bits 3-7 - Device Bits 8:15 - Bus Bits 16-23 - Segment Bits 24-31 - Bus Type If bits 24-31 are 0xff, then the definition is platform-specific.
