crypto: ccp: drop owner assignment from platform_drivers

2014-10-20T14:20:26+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

crypto: LLVMLinux: Remove VLAIS from crypto/ccp/ccp-crypto-sha.c

2014-10-14T08:51:23+00:00

Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99
compliant equivalent. This patch allocates the appropriate amount of memory
using a char array using the SHASH_DESC_ON_STACK macro.

The new code can be compiled with both gcc and clang.

crypto: ccp - Check for CCP before registering crypto algs

2014-09-24T06:23:34+00:00

If the ccp is built as a built-in module, then ccp-crypto (whether
built as a module or a built-in module) will be able to load and
it will register its crypto algorithms.  If the system does not have
a CCP this will result in -ENODEV being returned whenever a command
is attempted to be queued by the registered crypto algorithms.

Add an API, ccp_present(), that checks for the presence of a CCP
on the system.  The ccp-crypto module can use this to determine if it
should register it's crypto alogorithms.

PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use

2014-08-12T18:15:14+00:00

We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines.  This issue was reported by checkpatch.

A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):

// 

@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@

- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

crypto: ccp - Do not sign extend input data to CCP

2014-08-01T14:36:13+00:00

The CCP hardware interprets all numbers as unsigned numbers, therefore
sign extending input data is not valid.  Modify the function calls
for RSA and ECC to not perform sign extending.

This patch is based on the cryptodev-2.6 kernel tree.

crypto: ccp - Remove "select OF" from Kconfig

2014-07-24T08:52:12+00:00

The addition of the "select OF if ARM64" has led to a Kconfig
recursive dependency error when "make ARCH=sh rsk7269_defconfig"
was run.  Since OF is selected by ARM64 and the of_property_read_bool
is defined no matter what, delete the Kconfig line that selects OF.

crypto: ccp - Base AXI DMA cache settings on device tree

2014-07-23T13:28:38+00:00

The default cache operations for ARM64 were changed during 3.15.
To use coherent operations a "dma-coherent" device tree property
is required.  If that property is not present in the device tree
node then the non-coherent operations are assigned for the device.

Add support to the ccp driver to assign the AXI DMA cache settings
based on whether the "dma-coherent" property is present in the device
node.  If present, use settings that work with the caches.  If not
present, use settings that do not look at the caches.
