ccli8 51087a9f50 Fix DMA input/output buffers are overlapped in AES alter. 2018-01-12 15:01:47 +00:00
ccli8 5938e6b73a Remove unnecessary H/W context clone functions in SHA alter. 2018-01-12 15:01:47 +00:00
ccli8 2caeb92b5f Fix context clone corner case in SHA alter. 
As destination/source contexts are the same, we return immediately.
 2018-01-12 15:01:47 +00:00
ccli8 fd650adcee Fix indefinite loop in SHA alter. 2018-01-12 15:01:47 +00:00

ccli8 e352fc48bd Use interrupt signal rather than polling to check operation completion in DES alter. 
This is to be consistent with PRNG/AES.

ccli8 5498bdad87 Refine code with SHA context selection in SHA alter. 2018-01-12 15:01:46 +00:00
ccli8 2ba799462a Guard against SHA internal state size is not word-aligned in SHA alter. 2018-01-12 15:01:46 +00:00
ccli8 e1714d1d58 Fix SHA H/W resource leakage in context cloning 2018-01-12 15:01:46 +00:00
ccli8 e7f75b069f Fix SHA H/W is not stopped in corner case 
Take SHA1 for example, without the fix, SHA H/W is not stopped in either case:
(1) ctx->total == 0 in mbedtls_sha1_hw_finish()
(2) mbedtls_sha1_hw_finish() is not called by upper layer
 2018-01-12 15:01:46 +00:00
ccli8 402d2d26ec Strengthen crypto DMA buffer check 
1. Catch incompatible buffer range, where buffer base = 0xffffff00 and buffer size = 0x100.
2. Add buffer size alignment check.

ccli8 0b51602734 Refine AES/DES alter. DMA buffer requirement comment 2018-01-12 15:01:46 +00:00
ccli8 ad7024687e Fix compile error with disabled crypto 
For example, even though MBEDTLS_SHA512_C is disabled (via #undef MBEDTLS_SHA512_C),
mbedtls_sha512_context is still necessary due to referenced in sha512.h.
 2018-01-12 15:01:46 +00:00
ccli8 56087fe0a4 Fix compile error as mbedtls is not included 
Currently, trng_api.c is located in targets/ and AES/DES/SHA alter. are located in mbedtls/.
They have shared crypto code.
If they could locate at same location e.g. mbedtls/, the shared crypto code placement would be more reasonable.

ccli8 41f4e1a12c Coordinate crypto init among AES/DES/SHA/PRNG 
Add counter to track crypto init among crypto sub-modules. It includes:
1. Enable crypto clock
2. Enable crypto interrupt

As counter gets zero, crypto clock is disabled to save power.
