Hello, all

In ACPI spec 3.0, section 9.9 defines 4 objects for PATA/SATA:

_GTF is for both PATA and SATA, which is used to return ATA task file
needed to re-init the drive;
_SDD is SATA-only object, which is used to inform the platform of the
type of device attached to a port;
_GTM and _STM are PATA-only objects, which are used to get/set PATA
timing information(i.e. PIO and DMA speed).

It seems to be quite common for ICH*M notebooks to use the SATA ports
to attach PATA drives with PATA->SATA bridge chips in the middle.

In this case, one would expect the _GTM and _STM objects to be necessary,
even though Linux thinks it's a SATA situation.

Do the patches take this into account?

Cheers
