Subject: Marvell 88SE6141 (88SE614x) support

Hi,

I'm trying to get the 88SE6141 on my Asus M2N32 WS Professional working.
lspci shows this:
08:00.0 SATA controller: Marvell Technology Group Ltd. 88SE614x SATA II
PCI-E controller (rev 01)
or 08:00.0 0106: 11ab:6141 (rev 01) with -n.

Seeing the post on
http://www.nabble.com/kernel-support-for-Marvell-88SE614x-chipset-t2544905.html
I tried adding

{ PCI_VDEVICE(MARVELL, 0x6141), board_ahci_mv },        /* 6141 */

to drivers/ata/ahci.c - this is the result:

I actually can use the disk. Just formatted the disk, and testing with
some data. Only thing is the number of ports, worrying me a bit: ahci
0000:08:00.0: nr_ports (5) and implemented port map (0xf) don't match.
Also there is supposedly an IDE port on that chip as well that might not
work with this particular setup.

Regards,
Chris
