SCIS
SCI IRQ Select: Specifies on which IRQ the SCI will
internally appear. If not using the APIC, the SCI must be
routed to IRQ9-11, and that interrupt is not sharable with
the SERIRQ stream, but is shareable with other PCI
interrupts. If using the APIC, the SCI can also be mapped
to IRQ20-23, and can be shared with other interrupts.

010 IRQ11
011 Reserved
100 RQ20 (only if APIC enabled)
101 IRQ21 (only if APIC enabled)
110 IRQ22 (only if APIC enabled)
111 IRQ23 (only if APIC enabled)
Note: When the interrupt is mapped to APIC interrupts
9, 10 or 11, the APIC must be programmed for
active-high reception. When the interrupt is
mapped to APIC interrupts 20 through 23, the
APIC must be programmed for active-low
reception.

Offset 48h: GBA: GPIO Base Address Register
GBA sets the base address in I/O space for the GPIO I/O registers (see Section 22.2,
“General Purpose I/O-Mapped Configuration Register Details” on page 806). These
registers can be mapped anywhere in the 64 K I/O space on 64-byte boundaries.
