-Module produces Device I/O on top of PCI Root Bridge I/O for Segment 0 only.
-This is a valid assumption because many of the EFI 1.02/EFI 1.10 systems that may have provided
-Device I/O were single segment platforms. The goal of the ECP is to provide compatibility with the
-drivers/apps that may have used Device I/O.
-
-Device I/O is on list of deprecated protocols for UEFI 2.0 and later.
-This module module layers Device I/O on top of PCI Root Bridge I/O (Segment 0)
- Use if:
- There are no EDK modules present that produces Device I/O
- EFI drivers included that consume Device I/O
- Platform required to support EFI drivers that consume Device I/O
- Platform required to support EFI applications that consume Device I/O
