* crypto: ccp: Add Platform Security Processor (PSP) device supportBrijesh Singh2017-12-041-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | The Platform Security Processor (PSP) is part of the AMD Secure Processor (AMD-SP) functionality. The PSP is a dedicated processor that provides support for key management commands in Secure Encrypted Virtualization (SEV) mode, along with software-based Trusted Execution Environment (TEE) to enable third-party trusted applications. Note that the key management functionality provided by the SEV firmware can be used outside of the kvm-amd driver hence it doesn't need to depend on CONFIG_KVM_AMD.

* crypto: ccp: Build the AMD secure processor driver only with AMD CPU supportBorislav Petkov2017-12-041-0/+1
| | | | | | | | | | | | | | | This is AMD-specific hardware so present it in Kconfig only when AMD CPU support is enabled or on ARM64 where it is also used.

* crypto: ccp - select CONFIG_CRYPTO_RSAArnd Bergmann2017-08-091-0/+1
| | | | | | | | | | | | | | | Without the base RSA code, we run into a link error: ERROR: "rsa_parse_pub_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined! ERROR: "rsa_parse_priv_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined! Like the other drivers implementing RSA in hardware, this can be avoided by always enabling the base support when we build CCP.

* crypto: ccp - Introduce the AMD Secure Processor deviceBrijesh Singh2017-07-181-7/+14
| | | | | | | | | | | The CCP device is part of the AMD Secure Processor. In order to expand the usage of the AMD Secure Processor, create a framework that allows functional components of the AMD Secure Processor to be initialized and handled appropriately.

* crypto: drivers - Fix Kconfig selectsHerbert Xu2015-06-181-1/+0
| | | | | | | | | | | | | | | | This patch fixes a number of problems in crypto driver Kconfig entries: 1. Select BLKCIPHER instead of BLKCIPHER2. The latter is internal and should not be used outside of the crypto API itself. 2. Do not select ALGAPI unless you use a legacy type like CRYPTO_ALG_TYPE_CIPHER. 3. Select the algorithm type that you are implementing, e.g., AEAD. 4. Do not select generic C code such as CBC/ECB unless you use them as a fallback. 5. Remove default n since that is the default default. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
