------------------------------------------------------
Subject: pata: jmicron: Jmicron multifunction setup
From: Alan Cox <alan@xxxxxxxxxx>
JMicron controllers start out in life pretending to be a single legacy IDE
interface with the ports magically mangled into it. When prodding they turn
into a dual function device which has an AHCI controller for SATA and a PATA
controller for the PATA ports.
Do the prodding early enough that our PCI layer enumeration finds and
discovers the extra functions.
