2020-02-22crypto: ccree - improve kerneldoc in cc_sram_mgr.[ch]Geert Uytterhoeven
Miscellaneous improvements: - Start comment blocks with "/**" to enable kerneldoc, - Mark parameters using "@" instead of "\param", - Fix typos in parameter names, - Add missing function names to kerneldoc headers, - Add missing parameter and return value descriptions.

2020-02-22crypto: ccree - remove struct cc_sram_ctxGeert Uytterhoeven
The cc_sram_ctx structure contains only a single member, and only one instance exists. Simplify the code and reduce memory consumption by moving this member to struct cc_drvdata. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2020-02-22crypto: ccree - use u32 for SRAM addressesGeert Uytterhoeven
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.

2020-02-22crypto: ccree - remove bogus paragraph about freeing SRAMGeert Uytterhoeven
The SRAM allocator does not support deallocating memory. Hence remove all references to freeing SRAM. Fix grammar while at it. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2020-02-22crypto: ccree - remove empty cc_sram_mgr_fini()Geert Uytterhoeven
cc_sram_mgr_fini() doesn't do anything, so it can just be removed. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2018-02-15crypto: ccree - introduce CryptoCell driverGilad Ben-Yossef
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>
