* This provides ACPICA with the desired port protections and
* Microsoft compatibility.

* Description of port entries:
* DMA: DMA controller
* PIC0: Programmable Interrupt Controller (8259_a)
* PIT1: System Timer 1
* PIT2: System Timer 2 failsafe
* RTC: Real-time clock
* CMOS: Extended CMOS
* DMA1: DMA 1 page registers
* DMA1L: DMA 1 Ch 0 low page
* DMA2: DMA 2 page registers
* DMA2L: DMA 2 low page refresh
* ARBC: Arbitration control
* SETUP: Reserved system board setup
* POS: POS channel select
* PIC1: Cascaded PIC
* IDMA: ISA DMA
* ELCR: PIC edge/level registers
* PCI: PCI configuration space
