IDE connector on Promise 20376 SATA controller

IDE connector on Promise 20376 SATA controller

[Jesse Stockall]

Hi

I just purchased a board with a Promise 20376 SATA raid controller that
also has am IDE connector for a single PATA drive. The sata_promise
driver does not see the drive attached to the IDE connector.

I found a few old posts where people indicated that it was on Jeff
Garziks TODO list. 

kernel version 2.6.9-rc2-mm3

Thanks

Jesse

Still on the TODO list.  You (or anyone else) is welcome to work on this 
feature, I can describe to another engineer how to do it.

PATA+SATA controllers and libata (was Re: IDE connector on Promise 20376 SATA controller)

[Jeff Garzik]

The problems to solve, in order to support PATA and SATA on the same 
controller:

1) struct ata_probe_ent describes a single host controller.  It has a 
single struct ata_port_operations pointer.  To support PATA and SATA on 
the same controller, multiple ata_port_operations pointers must be 
supported.

2) struct ata_host_set uses a single struct ata_port_operations for the 
entire host controller.

Fix those two things, and support for PATA+SATA controllers is possible.
