New Atmel support (WOLFSSL_ATMEL) and port for ATECC508A (WOLFSSL_ATECC508A). Adds wolfCrypt support for ECC Hardware acceleration using the ATECC508A. Adds new PK callback for ECC shared secret. Fixed missing "wc_InitRng_ex" when using "CUSTOM_RAND_GENERATE_BLOCK". Added ATECC508A RNG block function for P-RNG bypass ability. Added internal "wolfSSL_GetEccPrivateKey" function for getting reference to private key for ECC shared secret (used in test.h for testing PK_CALLBACK mode). Added README.md for using the Atmel ATECC508A port.

Fix build issues with rebase for ECC and RSA. Changed user_settings.h example when LTC is enabled to disable Shamir and ECC-521. Cleanup to add USE_NXP_MMCAU and USE_NXP_LTC for the example user_settings.h, so the project file can automatically configure.

Fixes to include path for NXP ksdk_port. Fixes for time USER/OVERRIDES so their #ifdef's are checked first. Fix to initialize LTC via new "ksdk_port_init" function. Cleanup of the ksdk_port.c for formatting, macros, statics and line length. Cleanup of the AES code for key size. Cleanup of the wolfCrypt sha.c for readability. Added support for the KSDK bare metal drivers to the IDE Rowley CrossWorks example. Updated the settings.h to allow for overrides in Freescale section. Updated README with info for using LTC.

Fix for ECC with !WC_NO_CACHE_RESISTANT and ALT_ECC_SIZE causing invalid mp_int*. An ecc_point with ALT_ECC_SIZE is "mp_int* x" vs. "mp_int x[1]". The resulting pointer for &M[0]->x is not valid in the ALT_ECC_SIZE case. This was found while testing ECC on a Cortex M4 (32-bit) and caused a hard fault.

Added asynchronous wolfCrypt RSA, TLS client and Cavium Nitrox V support. Asynchronous wolfSSL client support for "DoServerKeyExchange", "SendClientKeyExchange", "SendCertificateVerify" and "DoCertificateVerify". Fixes for async DTLS. Refactor of the wolf event and async handling for use in wolfCrypt. Refactor of the async device support so its hardware agnostic. Added Cavium Nitrox V support (Nitrox tested using SDK v0.2 CNN55XX-SDK with new configure "--with-cavium-v=/dir" option). Moved Nitrox specific functions to new port file "port/cavium/cavium_nitrox.c". RSA refactor to handle async with states. RSA optimization for using dpraw for private key decode. Use double linked list in wolf event for faster/cleaner code. Use typedef for wolf event flag. Cleanup of the async error codes. wolfCrypt test and benchmark support for async RSA. Asynchronous mode enabled using "./configure --enable-asynccrypt". If no async hardware is defined then the internal async simulator (WOLFSSL_ASYNC_CRYPT_TEST) is used. Note: Using async mode requires async.c/h files from wolfSSL. If interested in using asynchronous mode please send email to info@wolfssl.com.

Fixed possible issue with OID pointer returned from "wc_ecc_get_oid" if "HAVE_OID_ENCODING" enabled. Was previously returning static pointer, which was shared for all OID's. Now uses cache for each OID, which also improves performance on subsequent calls to the same OID.

Adds new "HAVE_ECC_BRAINPOOL", "HAVE_ECC_KOBLITZ", "HAVE_ECC_SECPR2" and "HAVE_ECC_SECPR3" options. ECC refactor to use curve_id in _ex functions. NID and ECC Id's match now. Added ability to encode OID (HAVE_OID_ENCODING), but leave off by default and will use pre-encoded value for best performance.

Fixes for compressed keys. Fix to fast math "mp_cnt_lsb" to return proper value, which fixes "mp_jacobi", which fixes "mp_sqrtmod_prime", which fixes compressed keys for 224-bit key. Removed workarounds for compressed keys. Added new configure option "--enable-compkey". Fixed issue with normal math and custom curves where "t2" could be free'd and used. Fixed issue with mp_dump in integer.c, with not allocating correctly sized buffer for toradix.

Fix in mp_jacobi to also handle case of a == 0. Cleanup of *_ecc_mulmod and wc_ecc_make_key_ex error handling. Cleanup of ecc_map for handling normal, fast and alt_ecc math for optimization of performance and allowing reduced ecc_size.
