pata_acpi: ACPI driver support

	On a cable there may be
	eighty wires or perhaps forty
	and we learn about its type
	In the world of ACPI

	So we call the GTM
	And we find the the timing rate
	And we look through it to see
	If eighty wire it must be

	Timing lives in ACPI routines
	ACPI routines, ACPI routines
	Timing lives in ACPI routines
	ACPI routes ACPI routines

	And the drivers last you see
	Picking up unknown pci ids
	and the code begins to work

	Timing lives in ACPI routines
	ACPI routines, ACPI routines
	Timing lives in ACPI routines
	ACPI routes ACPI routines

	[Full speed ahead, Mr Hacker, full speed ahead]
	 Full speed over here sir!
	 Checking Cable, checking cable
	 Aye aye, 80 wire,
	 Heaven heaven]

	If we use ACPI (ACPI)
	Every box (every box) has all we need (has all we need)
	Cable type (cable type) and mode timing (mode timing)
	In our ATA (in our ATA) subroutines (subroutines, ha ha)

	Timing lives in ACPI routines
	ACPI routines, ACPI routines
	Timing lives in ACPI routines
	ACPI routes ACPI routines
	Timing lives in ACPI routines
	ACPI routines, ACPI routines
	Timing lives in ACPI routines
	ACPI routes ACPI routines
