On STM32MP15, OTP area may be read/written by using BSEC (boot, security and OTP control). BSEC registers set is composed of various regions, among which control registers and OTP shadow registers. Secure monitor calls are involved in this process to allow (or deny) access to the full range of OTP data. This adds support for reading and writing OTP data using SMC services. Data content can be aligned on 16-bits or 8-bits. Then take care of it, since BSEC data is 32-bits wide.
