Base Address Upper (BAU) — R/WO. This field is programmed by platform BIOS to
match the upper 32-bits of base address of the (G)MCH RCRB that is attached to this
RCRB.
Base Address Lower (BAL) — R/WO. This field is programmed by platform BIOS to
match the lower 32-bits of base address of the (G)MCH RCRB that is attached to this
RCRB.
Target Port Number (PN) — RO. Indicates the target port number is 1h (root port
#1).
Target Component ID (TCID) — R/WO. This field returns the value of the ESD.CID
(offset 0104h, bits 23:16) field programmed by platform BIOS, since the root port is
in the same component as the RCRB.
Reserved
Link Type (LT) — RO. Indicates that the link points to a root port.
Link Valid (LV) — RO. When FD.PE1D (offset 3418h, bit 16) is set, this link is not
valid (returns 0). When FD.PE1D is cleared, this link is valid (returns 1).
Reserved
Reserved
Bus Number (BN) — RO. Indicates the root port is on bus #0.
Device Number (DN) — RO. Indicates the root port is on device #28.
Function Number (FN) — RO. Indicates the root port is on function #0.
