Fix Promise SATAII 150 TX4 (PDC40518) and Promise SATA 300 TX4
(PDC40718-GP) wrong port enumeration order that makes it (nearly)
impossible to deal with boot problems using two or more drives.

The current kernel driver assumes:
port 1 - scsi3
port 2 - scsi1
port 3 - scsi0
port 4 - scsi2
The current kernel driver assumes nothing, but simply exports what the
hardware gives us.
It sounds like you are trying to patch the kernel because you received
an incorrectly-wired board. NAK.

I have tested two SATAII150TX4 (chip PDC40518 id: 105a:3d18 (rev 02))
adapters and one SATA300TX4 (chip PDC40718-GP id: 105a:3d17 (rev 02))
adapter on three different boards in last several days with exactly the
same results.
The problem disappears when using the driver form the www.promise.com site.
BIOS, Grub and promise.com driver agree the printed and documented port
order is correct but the current kernel driver exports (wrong) 3-2-4-1
port order.
Thanks,
Milan
