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 <ion@agorria.com>
Now that we have working AES engine driver we can request the warmboot code to be encrypted and signed with SBK if the device requires so. This unlocks LP0 support for most devices in the wild as they use ODM Production Secure. We are not aware of any "ODM Production Open" device nor have access to thus this has not been tested on one, merely added for completeness. Signed-off-by: Ion Agorria <ion@agorria.com>
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>
