Hi Jeff,
I'm working on ULI1575 SATA driver which I want to run in Emulated-PATA
mode.
I have the following understanding to run a SATA device in
Emulated-PATA mode:
1. In Emulated-PATA mode the legacy IDE driver should access the SATA
device directly in combined mode.
2. The class code of the device shlould be set to Emulated-PATA
mode(0x0185).
3. Enable SATA in combine mode.
After doing the above changes the driver does not work in Emulated-PATA
mode.
Is there something missing to make the driver work in Emulated-PATA mode?
Use a PCI quirk to unconditionally disable emulated PATA mode, because
it's not needed.
