Tian Hao 26a3cb93c7 component/soc : move dport access header files to soc 
1. move dport access header files to soc
2. reduce dport register write protection. Only protect read operation

Tian Hao f7e8856520 component/esp32 : fix dualcore bug 
1. When dual core cpu run access DPORT register, must do protection.
2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.

Angus Gratton 88b264cfce mbedTLS SHA: Fix cloning of SHA-384 digests 
Hardware unit only reads 384 bits of state for SHA-384 LOAD,
which is enough for final digest but not enough if you plan to
resume digest in software.

Angus Gratton dfcb241850 mbedTLS SHA Acceleration: Add missing esp_sha_lock_engine() function 2016-11-22 20:57:01 +11:00
Angus Gratton 2561b68af8 hwcrypto: Fixes for disabling one hardware unit causing reset of a different unit 
ROM functions reset related units, but this can have problems in a
multithreaded environment.

Angus Gratton c48612e516 mbedTLS SHA acceleration: Allow concurrent digest calculation, works with TLS 
SHA hardware allows each of SHA1, SHA256, SHA384&SHA512 to calculate digests
concurrently.

Currently incompatible with AES acceleration due to a hardware reset problem.

Ref TW7111.

Angus Gratton 46a9754b8e hwcrypto sha: Fix initialisation of SHA hardware in esp_shaX_start functions 
Problem exposed by previous commit.

Angus Gratton a32e954f67 hwcrypto sha: Feed one block at a time to hardware SHA implementation 
Fixes a bug where some longer block sizes produced incorrect results.

Angus Gratton 0a970e3a25 hwcrypto: Match API completely to mbedTLS naming conventions 2016-09-08 16:47:31 +08:00
Angus Gratton 2580c07ae6 esp32 hwcrypto: Make SHA-224 an obvious no-op for now 
This is not the long term solution...

Angus Gratton 0647d1e922 esp32 hwcrypto: Rework hardware crypto locking 
Should protect against concurrent use of hardware crypto primitives,
with good performance.

Not necessary to call esp_aes_acquire_hardware(),
esp_sha_acquire_hardware(), etc when using these APIs. These are
provided for external users calling the hardware crypto hardware
directly, to coexist with this implementation.
