[RFT PATCH] arm: omap1_defconfig: convert to use libata PATA drivers

[RFT PATCH] arm: omap1_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 omap1_defconfig to use libata PATA
drivers.

Build tested only.
If you have affected hardware please test.  Thank you.

All my omap1 devices are in a rack using NFSroot or MMC so
I can't test this. Seems like a good idea to me thoug, and does
not cause merge conflicts. So if you want to queue this via
along with other PATA related patches, please feel free to
add:

Thank you.

Arnd/Olof, could you please merge this patch?

Can you send the two patches in question again, and add arm@kernel.org
to Cc? I have trouble pulling them out of the archive at the moment.
