8 Secure boot module
The security module comprsises two parts: a configuration register (32 bits), and
a one time programmable memory to store program code. The security register
has the following layout:
The memory itself comprises four sectors containing 2KBytes each. The banks
are organised contiguously and can be used as a single 8KByte bank, but each
sector can be locked independently if required.
The OTP memory is programmed using three special I/O ports: the OTP address
port is a 16-bit port with resource ID 0x100002XX, the OTP data is written via
a 32-bit port with resource ID 0x200001XX, and the OTP control is on a 16-bit
port with ID 0x100003XX.
