crypto: ccp - Enable support for AES GCM on v5 CCPs

2017-03-24T14:02:55Z

A version 5 device provides the primitive commands required for AES GCM. This patch adds support for en/decryption. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

2017-03-24T14:02:55Z

Wire up support for Triple DES in ECB mode. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Add SHA-2 384- and 512-bit support

2017-03-24T14:02:54Z

Incorporate 384-bit and 512-bit hashing for a version 5 CCP device Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Assign DMA commands to the channel's CCP

2017-03-16T09:43:08Z

The CCP driver generally uses a round-robin approach when assigning operations to available CCPs. For the DMA engine, however, the DMA mappings of the SGs are associated with a specific CCP. When an IOMMU is enabled, the IOMMU is programmed based on this specific device. If the DMA operations are not performed by that specific CCP then addressing errors and I/O page faults will occur. Update the CCP driver to allow a specific CCP device to be requested for an operation and use this in the DMA engine support. Cc: # 4.9.x- Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - fix typo "CPP"

2016-10-25T03:08:28Z

The abbreviation for Cryptographic Coprocessor is "CCP". Signed-off-by: Paul Bolle Acked-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Let a v5 CCP provide the same function as v3

2016-08-09T10:47:16Z

Enable equivalent function on a v5 CCP. Add support for a version 5 CCP which enables AES/XTS/SHA services. Also, more work on the data structures to virtualize functionality. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Register the CCP as a DMA resource

2016-04-20T09:50:06Z

The CCP has the ability to provide DMA services to the kernel using pass-through mode of the device. Register these services as general purpose DMA channels. Changes since v2: - Add a Signed-off-by Changes since v1: - Allocate memory for a string in ccp_dmaengine_register - Ensure register/unregister calls are properly ordered - Verified all changed files are listed in the diffstat - Undo some superfluous changes - Added a cc: Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - CCP versioning support

2016-03-11T13:19:16Z

Future hardware may introduce new algorithms wherein the driver will need to manage resources for different versions of the cryptographic coprocessor. This precursor patch determines the version of the available device, and marks and registers algorithms accordingly. A structure is added which manages the version-specific data.

crypto: ccp - Check for CCP before registering crypto algs

2014-09-24T06:23:34Z

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.
