[PATCH] libata: support for SiS AHCI controller in SiS966/SiS968

[PATCH] libata: support for SiS AHCI controller in SiS966/SiS968

[David Wang]

Hi all,
My name is David Wang, working for SiS now.
This is my first try to post mail here.

This patch, against 2.6.17.11, adds support for SiS AHCI controller.
Device IDs, 0x1184 and 0x1185 are 1.5Gbps AHCI in SiS966 south bridge.
Device ID 0x0186 is 3Gbps AHCI in next SiS968.

While I load the driver, dmesg gives:
ahci 0000:00:05.0: version 1.2
ACPI: PCI Interrupt 0000:00:05.0[A] -> Link [LNKB] -> GSI 11 (level, low) ->

SCSI device sda: 160836480 512-byte hdwr sectors (82348 MB)

It seems running well with my several SATA devices.
If you need more information about the hardware or request a motherboard for
testing,
Contact me or Hank lee (mlee08@sis.com).

These are in the #upstream branch, FWIW...
