The security engine (SE) is responsible for the crypto done on the switch. SE is mapped to physical address 0x70012000.
The Nintendo Switch uses Tegra's Security Engine (SE) for handling cryptographic opearations at the system's lowest level.
The SE driver is mapped to physical address 0x70012000 with a total size of 0x2000 bytes and exposes several registers for programming the Security Engine.
