//
// The following illustrates the sample ASL code for a Combined
// and non-combined mode configuration.
//
// The SATA controller supports several configurations. Combined
// mode and non-Combined mode. If in non-Combined mode (P-ATA and
// SATA are separate PCI functions), then:
//
Port 0 == logical primary master
//
Port 1 == logical secondary master
//
//
Port 0 == logical secondary master
//
Port 1 == logical primary master
//
// Note that a separate P-ATA device namespace is required in the
// event that non-Combined mode is used.
//
// If in Combined mode (P-ATA and SATA combined as a single PCI
// function) then:
// Assumes SATA Port 0 and Port 1 are a single logical channel
// (primary/secondary BIOS selectable)
//
// Assumes P-ATA (physical primary or secondary channel) is a
// logical channel.(primary/secondary BIOS selectable).
//
// Possible Combined mode configurations:
//
Port 0 == primary master
//
Port 1 == primary slave
//
P-ATA
//
//
Port 0 == primary slave
//
Port 1 == primary master
//
P-ATA
//
//
P-ATA
//
Port 0 == secondary master
//
Port 1 == secondary slave
