This patch disables deprecated IDE subsystem in assabet_defconfig
(no IDE host drivers are selected in this config so there is no
valid reason to enable IDE subsystem itself).

I think the series makes a lot of sense. I have checked your assertions
in the changelogs and found no flaws in your logic, so I think we should
take them all through arm-soc unless there are other concerns.
Thank you.

Should I resend everything or just patches that were not reposted yet
(the ones that were marked as RFT initially and got no feedback)?
I'd be fine with just getting a pull request with all the patches that
had no negative feedback and that were not already applied (if any).

Do you have a list of ARM defconfigs that keep using CONFIG_IDE and
how you determined that they need it?
The only such defconfig is davinci_all_defconfig which uses
palm_bk3710 host driver (CONFIG_BLK_DEV_PALMCHIP_BK3710).

I know that ARCH_RPC/ARCH_ACORN has a couple of special drivers that
have no libata replacement, are there any others like that, or are
they all platforms that should in theory work with libata but need
testing?
All platforms except ARCH_ACORN, ARCH_DAVINCI & ARCH_RPC should work
with libata.
Adding Sekhar and Kevin for DaVinci: At first sight, palm_bk3710 looks
fairly straightforward (meaning someone has to do a few day's work)
to convert into a libata driver.

As this is on on-chip controller that is part of a dm644x and dm646x,
it should also not be hard to test (as long as someone can find
a hard drive to plug in).
I have a hard drive, but don't have any dm64xx hardware anymore to test
this.  My last working dm644x board died last year.
I have a working DM6446 EVM. I was able to connect a hard drive to it
and do some basic tests with v4.6 kernel.

I will look into converting the driver to libata. Might take some time
because this is unfamiliar territory for me.
Do you need some help with it?

I can provide you with draft driver patch if you want.
A draft driver patch will really help. I can test/debug. Otherwise, not
sure when I will really be able to get to this.

Regards,
Sekhar
