Add an API for OTP (one-time programmable) memory on stm32h5. There are OTP APIs for non-STM32 platforms. There is no other API for STM32 so far with these names. Implement it in stm32h563xx_flash.c since the progmem abstraction also lives there. int stm32_otp_write(const uint16_t *data, uint16_t len, uint32_t offset); int stm32_otp_read(uint16_t *data, uint16_t len, uint32_t offset); The API allows cross-block reads/writes that don't necessarily start/end at block boundaries. The type of `data` is uint16_t * to express to the caller that the pointer should be 2-aligned. The natural size of OTP words is 16 bits. `len` is uint16_t for no strong reason. Preserve author's work. uint32_t stm32_otp_getlockstatus(void); Get a mask of blocks that are locked. A block being locked is considered as being one-time programmed.
