[PATCH] sparc64: sparc64_defconfig: convert to use libata PATA drivers

[PATCH] sparc64: sparc64_defconfig: convert to use libata PATA drivers

[Bartlomiej Zolnierkiewicz]

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts sparc64_defconfig to use libata PATA
drivers.

For what it's worth, I've been using libata on sparc64 for roughly two 
years with no issues to report. All of my PATA machines have ALI 
controllers, not sure if any other controllers were ever used in sparc 
gear.

The Ultra 5 uses a CMD64x controller.

That said, last time I tried to get that machine working, I couldn't
partition the disk due to bugs in that driver.

I believe the Ultra 10 uses the same motherboard so it's likely also
affected. I believe these were in the first generation of "PC" like
SPARC workstations.

Thanks,

Yes, Ultra 5 uses CMD64x. This has worked well for me on U5 for ages. 
The debug messages have also been there as long as I remember. The 
controller is limited to 128GiB disks in DMA mode so I have used up to 
120G disks only and have not tried any bigger ones.

Yes, Ultra 10 uses the same mainboard but in a more roomy tower case. My 
U10 has addon PCI SCSI controller so I'm not testing IDE there.

Oh, the last time I tried, I had trouble partitioning the disk due to
it seemingly not writing beyond the first sector. I'll have to try
again.

FWIW QEMU's qemu-system-sparc64 emulator also uses the cmd646 controller
and can boot vmlinuz/initrd binaries directly for testing.
