crypto: cavium - Add Support for Octeon-tx CPT Engine Enable the Physical Function driver for the Cavium Crypto Engine (CPT) found in Octeon-tx series of SoC's. CPT is the Cryptographic Accelaration Unit. CPT includes microcoded GigaCypher symmetric engines (SEs) and asymmetric engines (AEs).

crypto: cavium - fix Kconfig dependencies The driver fails to build if MSI support is disabled: In file included from /git/arm-soc/drivers/crypto/cavium/cpt/cptpf_main.c:18:0: drivers/crypto/cavium/cpt/cptpf.h:57:20: error: array type has incomplete element type 'struct msix_entry' struct msix_entry msix_entries[CPT_PF_MSIX_VECTORS]; ^~~~~~~~~~~~ drivers/crypto/cavium/cpt/cptpf_main.c: In function 'cpt_enable_msix': drivers/crypto/cavium/cpt/cptpf_main.c:344:8: error: implicit declaration of function 'pci_enable_msix';did you mean 'cpt_enable_msix'? [-Werror=implicit-function-declaration] On the other hand, it doesn't seem to have any build dependency on ARCH_THUNDER, so let's allow compile-testing to catch this kind of problem more easily. The 64-bit dependency is needed for the use of readq/writeq.
