2020-02-22crypto: ccree - use u32 for SRAM addressesGeert Uytterhoeven1-1/+1
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. Signed-off-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2020-02-22crypto: ccree - make mlli_params.mlli_virt_addr void *Geert Uytterhoeven1-1/+1
mlli_params.mlli_virt_addr is just a buffer of memory. This allows to drop a cast. No change in generated code. Signed-off-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2020-02-13crypto: ccree - protect against empty or NULL scatterlistsGilad Ben-Yossef1-0/+1
Deal gracefully with a NULL or empty scatterlist which can happen if both cryptlen and assoclen are zero and we're doing in-place AEAD encryption. This fixes a crash when this causes us to try and map a NULL page, at least with some platforms / DMA mapping configs.

2018-02-15crypto: ccree - introduce CryptoCell driverGilad Ben-Yossef1-0/+59
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 <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
