Kernel/Hardware Support/OTP

The OTP is now exposed as a nvmem driver, read it from /sys/bus/nvmem/devices/wiiu-otp0/nvmem.

It has the same limitations as CafeOS, that is, if a section has been disabled it won’t be reenabled before a reboot.

This can then be used to implement access to encrypted data, be it the eMMC, discs, external USB devices, or anything else using one of the keys stored in here.

See WiiUBrew for more details.
