* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
Kbuild: Use dtc's -d (dependency) option
dtc: Implement -d option to write out a dependency file
kbuild: Fix comment in Makefile.lib
scripts/genksyms: clean lex/yacc generated files
kbuild: Correctly deal with make options which contain an "s"
This hooks dtc into Kbuild's dependency system.
Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
lack of this feature recently caused me to have very confusing "git
bisect" results.
For ARM, it's obvious what to add to $(targets). I'm not familiar enough
with other architectures to know what to add there. Powerpc appears to
already add various .dtb files into $(targets), but the other archs may
need something added to $(targets) to work.

So I've had one of these for a while and it looks like the vendor never
bothered submitting the support upstream.
This adds it using ppc40x_simple and provides a device-tree.
There are some changes to the boot wrapper because the way u-boot works
on this thing, it seems to expect a multipart image with the kernel,
initrd and dtb in it.
The USB support is missing as it needs the yet unmerged driver for
the DWC OTG part and the GPIOs may need further definition in the dts.

This adds a skeletton for the new Power "Non Virtualized"
platform which will be used by machines supporting running
without an hypervisor, for example in order to run KVM.
These machines will be using a new firmware called OPAL
for which the support will be provided by later patches.
The PowerNV platform is intended to be also usable under
the BML environment used internally for early CPU bringup
which is why the code also supports using RTAS instead of
OPAL in various places.

This is a first cut at making bootwrapper code which will
produce a zImage compliant with the requirements set down
by ePAPR.
This is a very simple bootwrapper, taking the device tree
blob supplied by the ePAPR boot program and passing it on
to the kernel. It builds on the earlier patch to build a
relocatable ET_DYN zImage to meet the other ePAPR image
requirements.
For good measure we have some paranoid checks which will
generate warnings if some of the ePAPR entry condition
guarantees are not met.

Commit ac4c2a3bbe broke the build
of all powerpc boot wrappers.
It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.
We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.
It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).
This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.
This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

JFFS2 uses lesser compression ratio and inflate always ends up in "copy
direct from output" case.
This patch tries to optimize the direct copy procedure. Uses
get_unaligned() but only in one place.
The copy loop just above this one can also use this optimization, but I
havn't done so as I have not tested if it is a win there too.
On my MPC8321 this is about 17% faster on my JFFS2 root FS than the
original.

There are several variants of the SBC deployed, single/dual
ethernet+serial, and also 4MB/8MB flash variations. In the interest of
having a single kernel image boot on all boards, the cuboot shim detects
the differences and mangles the DTS tree appropriately.
With the exception of the CF interface that was never populated on
production boards, this code/DTS supports all boardpop options.
