Kamalesh Babulal 817bb33433 Staging: sep: SEP driver build breaks with CONFIG_PCI=n
next-20090813 randconfig build breaks Discretix SEP driver when
configured with CONFIG_PCI=n.

drivers/staging/sep/sep_driver.c: In function 'sep_probe':
drivers/staging/sep/sep_driver.c:2548: error: implicit declaration of function 'pci_dev_get'

This patch adds the dependency on PCI for the DX SEP driver.

Alan Cox a4e80a1bcc Staging: sep: untangle the register_fs code
While goto can be useful for cleaner cleaning up in C (as Linux sometimes
does and I think Linus borrowed stylistically from Amiga) you can overdo it.
Here is a fine fine example of when it's overkill

#1: sep->cache_addr is assigned to sep->rar_addr and never changed
    sep->rar_addr is never assigned after this point

#2: sep->cache_bus ditto for sep->rar_bus

#3  sep->rar_region_addr is assigned but necer used

#4  sep->io_addr is in fact private to the probe function and
    the same as the reg_addr

#5  The remainig sep->io fields are in fact function locals

#6  sep->message_shared_area is assigned once from sep->shared_area
    sep->shared_area does not then change

#7  sep->shared_addr and sep->shared_area_addr are the same thing, ditto
    for the bus addresses.

Start by removing unused fields and then work this back to eliminate unused
chunks of the firmware loading ioctl (ie almost all of it)

Also fix the wrong handling of shared allocations and allocate the rar
region properly with dma_alloc_coherent not kmalloc, as it is device shared.

Alan Cox ca605bb68c Staging: sep: Use filp->private_data to create proper device instances
Move from using a sep_dev global. The workqueue still uses it and we use the
pointer in order to know if a device was found.

This requires some restructuring as the pci probe and the init module logic
are all rather messed up and only worked by luck.

Mark Allyn cd1bb431d8 Staging: sep: Upstream revision 3 of the security processor kernel driver
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.
