[PATCH 0/3] nvmem: Add Nuvoton NPCM OTP driver

[Kuan-Wei Chiu]

Add support for the OTP memory controllers found on Nuvoton NPCM7 SoCs.

This OTP is read-only and manages two independent arrays: Key Storage
and Fuse Array, which contain cryptographic keys, hardware strapping,
and calibration data. Each array provides 1024 bytes of storage.

You can use qemu-system-arm -M npcm750-evb to play around with it.
