The SEC4 supercedes the SEC2.x/3.x as Freescale's
Integrated Security Engine.  Its programming model is
incompatible with all prior versions of the SEC (talitos).

The SEC4 is also known as the Cryptographic Accelerator
and Assurance Module (CAAM); this driver is named caam.

This initial submission does not include support for Data Path
mode operation - AEAD descriptors are submitted via the job
ring interface, while the Queue Interface (QI) is enabled
for use by others.  Only AEAD algorithms are implemented
at this time, for use with IPsec.

Many thanks to the Freescale STC team for their contributions
to this driver.

This binding documents several properties that have been in use for quite
some time, and adds one new property 'pic-no-reset', which controls the
runtime initialization behavior of the PIC.  More specifically, the presence
of 'pic-no-reset' mandates that the PIC shall not be reset during runtime
initialization and that any initialization related to interrupt sources
shall be limited to sources explicitly referenced in the device tree.  This
functionality is useful in AMP systems where multiple OSes are sharing the
PIC and the reinitialization of the PIC can interfere with OSes that are
already up and running.

The interrupt specifier definition is based off of Stuart Yoder's FSL MPIC
binding.

This allows to load the OF driver based informations from the device
tree. Systems without BIOS may need to perform some initialization.
PowerPC creates a PNP device from the OF information and performs this
kind of initialization in their private PCI quirk. This looks more
generic.

This patch also avoids registering the platform RTC driver on X86 if
we have a device tree blob. Otherwise we would setup the device based
on the hardcoded information in arch/x86 rather than the device tree
based one.

History:
v1..v2:
- dropped device_type except for cpu & pci. I have the compatible string
  for pci so I can drop the device_type once it is possible
- I lowercased all compatible types. I will need to resend some patches
  which have upper case intel
- The cpu had the same compatible string as the soc node. So I added to
  the soc node -immr for internel memory mapped registers.
- I added generic names for all parts.
- I reworked the i2c bars matching the way you suggested. I added a
  compatible node for the PCI device which only the PCI ids in its
  compatible string. The bars (each represents a complete i2c
  controller) have a "intel,ce4100-i2c-controller" compatible node. It
  is not used by the driver.
  The driver is probed via PCI ids (by the pci subsystem not OF) and
  matches the bar address against the ressource in the child node. Once
  there is a hit the node is attached.
- The SPI driver is also probed via pci. However I also attached a
  compatible property based on PCI ids

v2..v3:
- intel,ce4100-immr become intel,ce4100-cp. cp stands for core
  peripherals. The Atom data sheet talks here about ACPI devices. Since
  we don't have ACPI this does not apply here.
- The interrupt map is gone. There are now plenty of device nodes.
- The "unit address string" got fixed, it uses not DD,V format.

v3..v4:
- added descriptions for compatible nodes introduced here:
  - intel,ce4100-ioapic
  - intel,ce4100-lapic
  - intel,ce4100-hpet
  - intel,ce4100
  - intel,ce4100-cp
  - intel,ce4100-pci
- added a description about I2C controller magic.
- Added gpio-controller and gpio-cells property to gpio devices. Those
  properties are not (yet) used.

This patch adds minimal support for device tree on x86. The device
tree blob is passed to the kernel via setup_data which requires at
least boot protocol 2.09.

Memory size, restricted memory regions, boot arguments are gathered
the traditional way so things like cmd_line are just here to let the
code compile.

The current plan is use the device tree as an extension and to gather
information which can not be enumerated and would have to be hardcoded
otherwise. This includes things like 
   - which devices are on this I2C/SPI bus?
   - how are the interrupts wired to IO APIC?
   - where could my hpet be?
