crypto: ccp - Add support for valid authsize values less than 16

2019-08-16T08:10:51Z

commit 9f00baf74e4b6f79a3a3dfab44fb7bb2e797b551 upstream. AES GCM encryption allows for authsize values of 4, 8, and 12-16 bytes. Validate the requested authsize, and retain it to save in the request context.

crypto: ccp - Fix XTS-AES-128 support on v5 CCPs

2017-08-04T01:27:41Z

Version 5 CCPs have some new requirements for XTS-AES: the type field must be specified, and the key requires 512 bits, with each part occupying 256 bits and padded with zeroes. cc: # 4.9.x+ Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Introduce the AMD Secure Processor device

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
