Security Engine

The Nintendo Switch uses Tegra's Security Engine (SE) for handling cryptographic opearations at the system's lowest level.

Registers

Erista only has one SE driver which is mapped to physical address 0x70012000 with a total size of 0x2000 bytes.

Mariko has two SE drivers which are mapped to physical addresses 0x70012000 (SE1) and 0x70412000 (SE2), each with a total size of 0x2000 bytes.
