The patch adds a debug driver, which dumps the power states
of all the North complex (NC) devices. This debug interface is
useful to figure out the devices, which blocks the S0ix
transitions on the platform. This is extremely useful during
enabling PM on customer platforms and derivatives.
This submission is based on the submission from Mahesh Kumar P:

Add Intel Quark platform support. Quark needs to pull down all
unlocked IMRs to ensure agreement with the EFI memory map post
boot.
This patch adds an entry in Kconfig for Quark as a platform and
makes IMR support mandatory if selected.

The SGI Visual Workstation seems to be dead; remove support so we
don't have to continue maintaining it.

Following files contains code that is common to all intel mid
soc's. So renamed them as below.
mrst/mrst.c -> intel-mid/intel-mid.c
mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c
mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c
pci/mrst.c -> pci/intel_mid_pci.c
Also, renamed the corresponding header files and made changes
to the driver files that included these header files.
To ensure that there are no functional changes, I have compared
the objdump of renamed files before and after rename and found
that the only difference is file name change.

The Technologic Systems TS-5500 is an x86-based (AMD Elan SC520)
single board computer. This driver registers most of its devices
and exposes sysfs attributes for information such as jumpers'
state or presence of some of its options.
This driver currently registers the TS-5500 platform, its
on-board LED, 2 pin blocks (GPIO) and its analog/digital
converter. It can be extended to support other Technologic
Systems products, such as the TS-5600.

Based on code by Jun Nakajima but stripped of all the old x86 mach-foo
stuff and turned into a single file for the Goldfish virtual bus layer.
The actual created platform device and bus enumeration is portable between the
ARM and x86 Goldfish emulations.

This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOs
Driver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here also
This driver is inspired by leds-net5501.c by Alessandro Zummo.
Ideally, leds-net5501.c should also be moved to platform/geode.
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.

x86 has finally arrived in the embedded nightmare and will rapidly
grow SoC platform support in various flavours. So we need a place for
the platform support files. That also allows us to clean up the
dumpground which arch/x86/kernel has become over time.
