sata_mv: fix 8-port timeouts on 508x/6081 chips
Fix a longstanding bug for the 8-port Marvell Sata controllers (508x/6081), where accesses to the upper 4 ports would cause lost-interrupts / timeouts for the lower 4-ports. With this patch, the 6081 boards should finally be reliable enough for mainstream use with Linux. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
