switch(reg1 & 0x700) {
case 5:
info_hpt366.private_data = &hpt366_40;
break;
case 9:
info_hpt366.private_data = &hpt366_25;
break;
default:
info_hpt366.private_data = &hpt366_33;
break;
}
The above runs always default part. It should be "(reg1 & 0x700) >> 8".

gcc complains thusly:
drivers/ata/pata_artop.c: In function ‘artop_init_one’:
drivers/ata/pata_artop.c:429: warning: ‘info’ may be used uninitialized in this function
While this warning is indeed bogus, even with improved static analysis
and value range propagation, gcc will probably never be able to detect
this.
Add a BUG_ON() to trap invalid driver_data entries in the PCI table.

Don't write the same code twice, in two different functions, when they

* Replace needless 'n_ports > 2' check with a simple BUG_ON().
No existing driver ever wants more than 2 ports.
* Delete ATA_FLAG_NO_LEGACY check. No current driver uses
ata_pci_init_one(), that sets this flag.
* Move PCI_CLASS_PROG register read below pci_enable_device()
* Handle ata_device_add() failure

absent ports
This removes the layering violation where drivers have to fiddle
directly with EH flags. Instead we now recognize -ENOENT means "no port"
and do the handling in the core code.
This also removes an instance of a call to disable the port, and an
identical printk from each driver doing this. Even better - future rule
changes will be in one place only.

misreports it)
Our ATA probe code checks that a device is not reporting a diagnostic
failure during start up. Unfortunately at least one device seems to like
doing this - the Gigabyte iRAM.
This is only done for the master right now (which is fine for the iRAM
as it is SATA), as with PATA some combinations of ATAPI device seem to
fool the check into seeing a drive that isn't there if it is applied to
the slave.

Non-uniform ports handling got broken while updating libata to handle
those in the same host. Only separate irq for the non-uniform
secondary port was implemented while all other fields (host flags,
transfer mode...) of the secondary port simply shared those of the
first.
For ata_piix combined mode, which ATM is the only user of non-uniform
ports, this causes the secondary port assume the wrong type. This can
cause PATA port to use SATA ops, which results in bogus check on PCS
and detection failure.
This patch adds ata_probe_ent->pinfo2 which points to optional
port_info for the secondary port. For the time being, this seems to
be the simplest solution. This workaround will be removed together
with ata_probe_ent itself after init model is updated to allow more
flexibility.

The biggest change is that ata_host_set is renamed to ata_host.
* ata_host_set => ata_host
* ata_probe_ent->host_flags => ata_probe_ent->port_flags
* ata_probe_ent->host_set_flags => ata_probe_ent->_host_flags
* ata_host_stats => ata_port_stats
* ata_port->host => ata_port->scsi_host
* ata_port->host_set => ata_port->host
* ata_port_info->host_flags => ata_port_info->flags
* ata_(.*)host_set(.*)\(\) => ata_\1host\2()
The leading underscore in ata_probe_ent->_host_flags is to avoid
reusing ->host_flags for different purpose. Currently, the only user
of the field is libata-bmdma.c and probe_ent itself is scheduled to be
removed.
ata_port->host is reused for different purpose but this field is used
inside libata core proper and of different type.
