Marius Vikhammer	3b3826b61c	crypto: allocate all DMA descriptors to DMA capable memory. ... These were previously placed on the stack, but the stack could be placed in RTC RAM which is not DMA capable.	2021-12-08 16:10:18 +08:00
Marius Vikhammer	9b4ba3d707	crypto: initial S3 Beta 3 bringup and testing for SHA/AES/RSA/flash enc	2021-05-18 11:25:41 +08:00
Marius Vikhammer	fe71a8e340	aes/sha: use a shared lazy allocated GDMA channel for AES and SHA ... Removed the old dynamically allocated GDMA channel approach. It proved too unreliable as we couldn't not ensure consumers of the mbedtls would properly free the channels after use. Replaced by a single shared GDMA channel for AES and SHA, which won't be released unless user specifically calls API for releasing it.	2021-03-09 09:23:05 +08:00

Marius Vikhammer	457ce080ae	AES: refactor and add HAL layer ... Refactor the AES driver and add HAL, LL and caps. Add better support for running AES-GCM fully in hardware.	2020-12-10 09:04:47 +00:00
