morris	c159984264	separate rom from esp32 component to esp_rom ... 1. separate rom include files and linkscript to esp_rom 2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h" 3. Forward compatible 4. update mqtt	2019-03-21 18:51:45 +08:00
Angus Gratton	f141b29328	hwcrypto sha: Use spinlocks instead of semaphores for small state changes ... Significant performance improvement and smaller RAM footprint.	2019-01-23 04:59:44 +00:00
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.	2016-11-25 19:26:30 +11:00
Angus Gratton	dfcb241850	mbedTLS SHA Acceleration: Add missing esp_sha_lock_engine() function	2016-11-22 20:57:01 +11:00
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.	2016-11-22 20:42:38 +11:00
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...	2016-09-08 16:47:28 +08:00
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.	2016-09-08 16:47:13 +08:00
Angus Gratton	4167b68eef	esp32: Move hardware crypto implementation/headers to hwcrypto directories	2016-09-08 16:46:28 +08:00
