ccli8 ca44675086 [Nuvoton] Fix crypto AC management 
1. For SHA AC, use atomic flag to manage its ownership.
   (1) Nuvoton SHA AC doesn't support SHA context save & restore, so S/W
       SHA fallback has been supported before. To make non-blocking 'acquire'
       semantics clearer, introduce 'try_acquire' to substitute for 'acquire'.
   (2) No biting CPU due to mechanism above.
   (3) No deadlock due to mechanism above.
2. For AES/DES/ECC AC, change to mutex to manage their ownership.
   (1) Change crypto-misc.c to crypto-misc.cpp to utilize C++ SingletonPtr
       which guarantees thread-safe mutex construct-on-first-use.
   (2) With change to crypto-misc.cpp, add 'extern "C"' modifier to CRYPTO_IRQHandler()
       to avoid name mangling in C++.
   (3) No priority inversion because mutex has osMutexPrioInherit attribute
       bit set.
   (4) No deadlock because these AC are all locked for a short sequence
       of operations rather than the whole lifetime of mbedtls context.
   (5) For double mbedtls_internal_ecp_init() issue, it has been fixed in upper
       mbedtls layer. So no need to change ecc init/free flow.

ccli8 b16b1dbeb9 [M487] Fix return error code when ECC H/W acceleratioin is failed 2018-12-14 17:28:30 +08:00
Ron Eldor 9f4e752ef3 Modify HW accelerator drivers to new error code 
Have the HW accelearation drivers return the platform module
errors about feature unsupported, and hw acceleration failure,
because the moduel specific errors will be removed.

ccli8 aafbdc8d38 [NUC472/M487] Fix compile error with disabled crypto

ccli8 b0228d020d [NUC472/M487] 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.

2. Enable crypto interrupt

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