crypto: safexcel - Set DMA alignment explicitly

2022-12-09T10:45:00Z

This driver has been implicitly relying on kmalloc alignment to be sufficient for DMA. This may no longer be the case with upcoming arm64 changes. This patch changes it to explicitly request DMA alignment from the Crypto API. Signed-off-by: Herbert Xu

crypto: inside-secure - Add MaxLinear platform

2022-10-21T11:05:24Z

This is to add MaxLinear platform into compatible id. Firmware endianness option is added since MaxLinear firmware is in little endian format. Signed-off-by: Peter Harliman Liem Signed-off-by: Herbert Xu

crypto: inside-secure - Add fw_little_endian option

2022-10-21T11:05:24Z

This is to add fw_little_endian option, which can be used for platform which firmware is using little-endian (instead of big-endian). Signed-off-by: Peter Harliman Liem Signed-off-by: Herbert Xu

crypto: inside-secure - Expand soc data structure

2022-10-21T11:05:24Z

Currently platform data is assigned directly to version string(instead of struct). To make it more scalable, we move it to use data struct instead. This allows customization for individual platforms other than version string. Signed-off-by: Peter Harliman Liem Signed-off-by: Herbert Xu

crypto: inside-secure - Replace generic aes with libaes

2022-09-24T08:14:43Z

Commit 363a90c2d517 ("crypto: safexcel/aes - switch to library version of key expansion routine") removed CRYPTO_AES in the config. However, some portions of codes still rely on generic AES cipher (e.g. refer to safexcel_aead_gcm_cra_init(), safexcel_xcbcmac_cra_init()). This causes transform allocation failure for those algos, if CRYPTO_AES is not manually enabled. To resolve that, we replace all existing AES cipher dependent codes with their AES library counterpart.

crypto: inside_secure - Avoid dma map if size is zero

2022-09-24T08:14:42Z

From commit d03c54419274 ("dma-mapping: disallow .map_sg operations from returning zero on error"), dma_map_sg() produces warning if size is 0. This results in visible warnings if crypto length is zero. To avoid that, we avoid calling dma_map_sg if size is zero. Signed-off-by: Peter Harliman Liem Signed-off-by: Herbert Xu

crypto: inside-secure - Change swab to swab32

2022-09-16T10:29:44Z

The use of swab() is causing failures in 64-bit arch, as it translates to __swab64() instead of the intended __swab32(). It eventually causes wrong results in xcbcmac & cmac algo. Fixes: 78cf1c8bfcb8 ("crypto: inside-secure - Move ipad/opad into safexcel_context") Signed-off-by: Peter Harliman Liem Acked-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - Add missing MODULE_DEVICE_TABLE for of

2022-07-29T10:28:54Z

Without MODULE_DEVICE_TABLE, crypto_safexcel.ko module is not automatically loaded on platforms where inside-secure crypto HW is specified in device tree (e.g. Armada 3720). So add missing MODULE_DEVICE_TABLE for of. Fixes: 1b44c5a60c13 ("crypto: inside-secure - add SafeXcel EIP197 crypto engine driver") Signed-off-by: Pali Rohár Acked-by: Marek Behún Signed-off-by: Herbert Xu

crypto: inside-secure - fix packed bit-field result descriptor

2022-07-08T07:21:17Z

When mixing bit-field and none bit-filed in packed struct the none bit-field starts at a distinct memory location, thus adding an additional byte to the overall structure which is used in memory zero-ing and other configuration calculations. Fix this by removing the none bit-field that has a following bit-field. Signed-off-by: Ofer Heifetz Acked-by: Antoine Tenart Acked-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - Add MODULE_FIRMWARE macros

2022-05-06T10:16:55Z

The safexcel module loads firmware so add MODULE_FIRMWARE macros to provide that information via modinfo. Signed-off-by: Juerg Haefliger Acked-by: Antoine Tenart Signed-off-by: Herbert Xu
