[PATCH] Add Marvell 6141 PATA support to AHCI driver

2007-05-26 Thread Jeff Garzik
Here is a patch against 2.6.22-rc3 that adds support for both the PATA and SATA portions of the Marvell AHCI-like chip. The architecture for PATA is quite nice, mimicing AHCI very closely. Basic port scanning, interrupt handling, freezing and thawing is the same, and uses the same register
