* crypto: ccree - update register handling macrosHadar Gat2020-03-121-40/+37
| | | | | | | Changed CC_GENMASK macro so it can be used for all HW registers. Signed-off-by: Hadar Gat <hadar.gat@arm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: ccree - use u32 for SRAM addressesGeert Uytterhoeven2020-02-221-6/+4
| | | | | | | | | | | | SRAM addresses are small integer offsets into local SRAM. Currently they are stored using a mixture of cc_sram_addr_t (u64), u32, and dma_addr_t types. Settle on u32, and remove the cc_sram_addr_t typedefs. This allows to drop several casts.

* crypto: ccree - use existing helpers to split 64-bit addressesGeert Uytterhoeven2020-02-221-4/+4
| | | | | | | | | | | Use the existing lower_32_bits() and upper_32_bits() macros instead of explicit casts and shifts to split a 64-bit address in its two 32-bit parts. Drop the superfluous cast to "u16", as the FIELD_PREP() macro already masks it to the specified field width.

* crypto: ccree - avoid implicit enum conversionNathan Chancellor2018-10-171-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang warns when one enumerated type is implicitly converted to another and this happens in several locations in this driver, ultimately related to the set_cipher_{mode,config0} functions. set_cipher_mode expects a mode of type drv_cipher_mode and set_cipher_config0 expects a mode of type drv_crypto_direction. drivers/crypto/ccree/cc_ivgen.c:58:35: warning: implicit conversion from enumeration type 'enum cc_desc_direction' to different enumeration type 'enum drv_crypto_direction' [-Wenum-conversion] set_cipher_config0(&iv_seq[idx], DESC_DIRECTION_ENCRYPT_ENCRYPT); drivers/crypto/ccree/cc_hash.c:99:28: warning: implicit conversion from enumeration type 'enum cc_hash_conf_pad' to different enumeration type 'enum drv_crypto_direction' [-Wenum-conversion] set_cipher_config0(desc, HASH_DIGEST_RESULT_LITTLE_ENDIAN); drivers/crypto/ccree/cc_aead.c:1643:30: warning: implicit conversion from enumeration type 'enum drv_hash_hw_mode' to different enumeration type 'enum drv_cipher_mode' [-Wenum-conversion] set_cipher_mode(&desc[idx], DRV_HASH_HW_GHASH); Since this fundamentally isn't a problem because these values just represent simple integers for a shift operation, make it clear to Clang that this is okay by making the mode parameter in both functions an int.

* crypto: ccree - introduce CryptoCell driverGilad Ben-Yossef2018-02-151-0/+590
Introduce basic low level Arm TrustZone CryptoCell HW support. This first patch doesn't actually register any Crypto API transformations, these will follow up in the next patch. This first revision supports the CC 712 REE component. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
