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 <ion@agorria.com>

This provides a means to encrypt and decrypt data using the Tegra
|
|
Bit Stream Engine for Video/Audio. Also may provide a mean to
|
|
encrypt/decrypt/sign using already loaded device SBK.
