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.

+Todo's so far (from Alan Cox)
+- Fix firmware loading
+- Get firmware into firmware git tree
+- Review and tidy each algorithm function
+- Check whether it can be plugged into any of the kernel crypto API
+  interfaces
+- Do something about the magic shared memory interface and replace it
+  with something saner (in Linux terms)
