[PATCH 0/7][KERNEL] add usb and mei features

[tom.zanussi]

From: Tom Zanussi <tom.zanussi@intel.com>

This adds a few new features, one each for usb/[xeou]hci-hcd and
another for amt/mei, and refactors existing config options into a new
usb/base, which are then used in crownbay.

v2: after suggestions from Bruce and Darren of a preference for a more
flattened feature tree structure, moved all the features into a single
usb/ feature dir.  I did however retain the common 'base' feature
because inlining that in each feature would mean that the same common
set would be repeated in multiple config fragments if more than one usb
feature was included in a BSP.

Please pull into linux-yocto-3.2.

Thanks,

Tom

As things stand now, a BSP would have to include both the base and the
*hcd right?

include usb/base.scc
include ehci-hcd.scc

Seems to me we should manage the dependencies wherever we can. When I've
created fragments I've been including their requirements as well to make
it easier on the integrator. Since you've put the dependencies in their
own fragment, why not include the fragment in the *hcd.scc files?

Now if someone need only include the one line for the *hcd. Since it's
only a total of 3 lines of CONFIG settings we're packaging up here, it
seems to me we should be able to enable it with only 1 line of meta data.

Yes, this is exactly what I did in the previous patchset.

The problem is that if we do this for each of the *hcd fragments, we end
up with the options in base.cfg repeated for each, which may or may not
produce a config-check warning.

To avoid that, we need to be able to add the base.cfg items once
followed by the individual *hcd items as I did with the crownbay
example:

+include features/usb/base.scc
+include features/usb/ehci-hcd.scc
+include features/usb/ohci-hcd.scc
+include features/usb/uhci-hcd.scc

"May or may not"? If our tools complain about setting a config to the
same value, I would prefer to address that in the tools.

Bruce, any comment on the intended behavior of the tools?

Well, there is this in the tools:

# Egads. People are listing the same thing multiple times within a fragment.
#  An evil sin that deserves its own category (and insults).
KCONF_FRAG_ERRS=$KCONF_DIR/fragment_errors.txt

Tongue-in-cheek obviously, but is pointing out bad form regardless.

Anyway, the right way to solve this would be to implement fragment
dependencies, where each of the *hcd fragments would contain something
like

 depends-on base.scc
 kconf hardware ehci-hcd.cfg

and the tools would make sure only one instance of the base.scc options
was included.

Obviously we don't have that or anything like that planned (which would
probably be an upstreamable project, not something I wanted to address
with this relatively (I thought) minor cleanup).

That warning is supposed to only trigger if you literally are in the
same fragment. The switch to a new fragment should allow the duplication.

There is a secondary warning that yells if an option is redefined by
ANY fragment. That mode is to support a configuration scheme that says
all fragments should be exclusive and additive. I made that into a
flag some time ago.

That being said, the switch to merge_config (the upstream script), caused
a few things to be more difficult. This is one of them. I have some
changes to this already queued, and I'm not seeing anything like this
in my tests. I've got something that allows the multiple includes to
work fine (and stops short of a new keyword (although that it tempting
to reduce complexity)).

I'll run some configuration tests here when I merge the series, and see
if a regression snuck in.

Cheers,

Bruce

[PATCH 5/7][KERNEL] meta: add usb/uhci-hcd feature

[tom.zanussi]

From: Tom Zanussi <tom.zanussi@intel.com>

Add a 'uhci-hcd' feature that turns on the kernel options required to
support uhci (USB 1.x).
