ARM: tegra: Use AES engine for crypto functions

2025-08-01T05:43:41Z

Previously software based AES encryption was used with previously known device specific keys (SBK), now that we have AES driver we can simply delegate this to the engine without prior knowledge of the key (assuming it is still loaded). Signed-off-by: Ion Agorria

crypto: tegra: Add Tegra AES engine driver

2025-08-01T05:43:41Z

This driver allows using Tegra AES engines within BSEV and BSEA blocks to encrypt and decrypt data using different AES algorithms. One use case is allowing u-boot to self update by using the already loaded AES key in the engine's SBK slot by the bootrom. Particular care must be taken as chainloaded u-boot's may not have the SBK slot loaded as the vendor bootloader erases it before leaving it. Signed-off-by: Ion Agorria
