Re: [Linux-stm32] [PATCH] ARM: dts: stm32: enable STM32MP1 crypto/CRC accelerators unconditionally

Hi Ahmad, These IPs could be enabled in the secure side. To avoid any concurrency access, I prefer to keep all that crypto IPs status disable. For examples, RNG can be managed in OP-TEE, so it will remain disable in Linux. BR, Lionel On 1/19/21 10:52 AM, Ahmad Fatoum wrote: There is no
