Subject: sata_promise: unbreak 20619
From: Mikael Pettersson <mikpe@xxxxxxxx>
The PATA support patch for sata_promise appears, from code inspection, to
break the PATA-only 20619 chip.
The patch removes the SATA flag from the TX2plus SATA+PATA boards' common
flags, with the intention of adding it back via the _port_flags[] entries for
those boards' SATA ports.
However, it unconditionally marks ports 0 and 1 as SATA for all boards. This
causes the 20619 (TX4000) to announce its first two PATA ports as SATA |
ATA_FLAG_SLAVE_POSS.
I don't have a TX4000 so I don't know what the actual consequences of this bug
are, but surely this isn't Ok.
Fixed by moving the port 0 and 1 settings as SATA into the TX4 and TX2plus
specific initialisation code.
