This is basically a rewrite so there isn't a nice easy to present way of
providing this as a patch series. This patch is a pull of Mark's new driver into
the upstream staging area. On top of that are a series of patches by
Andy Shevchenko to make it build on the current tree, fix a few things and
even get it passed sparse.
The new driver supports the kernel crypto layer, passes the coding style checks,
passes human taste checks and has proper kernel-doc formatted comments.
I've then folded back in some later fixes it was missing that got applied to
to the kernel tree.
This should be ready for more serious review with a view to migration from
the staging tree shortly.

The Kconfig file should not have 'y' as the default, especially
as the driver will crash a machine if it is loaded and the hardware
is not present.

This driver is for the Security Processor, a dedicated encryption
and decryption driver that is used on the Intel mobile platform.
This has been checked with checkpatch and there are four
warnings for lines over 80 charactors.
There is one compile warning. This is for a function that is
only used if the rar register driver is needed. There is an
ifdef in a header file that stubs out the rar register driver
if the rar register is not configured.
This driver does add a configuration, which is CONFIG_DX_SEP.

It's currently stalled and the original submitter recommended that it
just be dropped at this point in time due.

configured with CONFIG_PCI=n.
drivers/staging/sep/sep_driver.c: In function 'sep_probe':

Upstream revision 3 of the security processor kernel driver;
now located in drivers/staging
This revision adds an initial TODO file
This driver no longer requires to have the firmware compiled in
it with the CONFIG_EXTRA_FIRMWARE configuration option.
Furthermore, we now have the right to distribute the firmware
binaries.
This is the Linux kernel driver for the Security Processor, which is
a hardware device the provides cryptographic, secure storage, and
key management services.
Please be aware that this patch does not contain any encryption
algorithm. It only transports data to and from user space
applications to the security processor.
