From Tony Lindgren:
Changes needed to drop legacy booting support for some
omap3 boards.

Note that that these are based on a merge of the
following for the dependencies:

- v3.12-rc5 for fixes to pinctrl mask
- omap-for-v3.13/dt-signed to avoid pointless merge conflicts
- omap-for-v3.13/quirk-signed for legacy pdata handling

tools/perf/build: Pass through DEBUG parameter

Arnaldo reported that 'make DEBUG=1' does not work anymore.

The reason is that 'Makefile' only passes it through to
'Makefile.perf' via the environment, but 'Makefile.perf'
checks that it's a command line option:

ifeq ("$(origin DEBUG)", "command line")
PERF_DEBUG = $(DEBUG)
endif

So pass it through properly, and also clean up DEBUG parameter
handling while at it and fix a couple of annoyances:

- DEBUG=0 used to be interpreted as 'debugging on'. Turn it
into 'debugging off' instead.

- Same was the case for 'DEBUG=' - turn that into debug-off
as well.

- Pass in just a clean, sanitized 'DEBUG' value and get rid of
the intermediate, unnecessary PERF_DEBUG variable.

tools/perf/build: Speed up the final link

libtraceevent.a and liblk.a rules have always-missed dependencies,
which causes python.so to be relinked at every build attempt - even
if none of the affected code changes.

This slows down re-builds unnecessarily, by adding more than a second
to the build time:

comet:~/tip/tools/perf> time make

...

SUBDIR /fast/mingo/tip/tools/lib/lk/
make[1]: `liblk.a' is up to date.
SUBDIR /fast/mingo/tip/tools/lib/traceevent/
LINK perf
GEN python/perf.so

real 0m1.701s
user 0m1.338s
sys 0m0.301s

Add the (trivial) dependencies to not force a re-link.

This speeds up an empty re-build enormously:

comet:~/tip/tools/perf> time make

...

real 0m0.207s
user 0m0.134s
sys 0m0.028s

[ This adds some coupling between the build dependencies of
libtraceevent and liblk - but until those stay relatively
simple this should not be an issue. ]

tools/perf/build: Speed up git-version test on re-make

util/PERF-VERSION-GEN is currently executed on every build attempt,
and this script can take a lot of time on trees that are at a
significant git-distance from Linus's tree:

$ time util/PERF-VERSION-GEN

real 0m4.343s
user 0m4.176s
sys 0m0.140s

It also takes a lot of time if the Git repository is network attached, etc.,
because the commands it uses:

TAG=$(git describe --abbrev=0 --match "v[0-9].[0-9]*" 2>/dev/null )

has to count commits from the nearest tag and thus has to access (and
decompress) every git commit blob on the relevant version path.

Even on Linus's tree it takes 0.28 seconds on a fast box to count all the
commits and get the git version string:

$ time util/PERF-VERSION-GEN

real 0m0.279s
user 0m0.247s
sys 0m0.025s

But the version string only has to be regenerated if the git repository's
head commit changes. So add a dependency of ../../.git/HEAD and touch
the file every time it's regenerated, so that Make's build rules can
pick it up and cache the result:

make: `PERF-VERSION-FILE' is up to date.
