Posted by Rayhan Faizel 6 months, 2 weeks ago

All BCM2835 boards have on-board OTP memory with 66 32-bit rows. Usually,
its contents are accessible via mailbox commands.

Rayhan Faizel (3):
  hw/nvram: Add BCM2835 OTP device
  hw/arm: Connect OTP device to BCM2835
  hw/misc: Implement mailbox properties for customer OTP and device
    specific private keys
