[PATCH 0/6] libata: Support SATA attached via SAS

[Brian King <brking@us.ibm.com>]

Jeff,

Here is a refresh of my patchset to allow SAS HBAs to use libata to
control attached SATA devices. It should apply cleanly to #upstream.

James,

After our discussion at the storage summit I think I have
a better idea what you are looking for with a SATA transport class.
Unfortunately, the problem I am facing is that I am dealing with a
firmware stack (ipr) which does not expose the physical transport
to the host. The ipr firmware does all the device discovery and reports
a configuration table describing the attached devices, but does not
export any physical topology information. At some point in the future
I hope to be able to extract this information from the ipr firmware
stack and convert ipr to be able to utilize the sas/sata transport class,
but, unfortunately, the firmware interfaces to accomplish this
aren't available at this time.

Brian
