Browse Source 
this is a rework of #5320 started by Andreas then abandoned.

same syntax as in stm32f2x driver:

  enable OTP for writing
  > stm32l4x otp 1 enable

  write to OTP
  > flash write_bank 1 foo.bin 0
  > flash filld 0x1FFF7000 0xDeadBeafBaadF00d 1

  read OTP
  > mdw 0x1FFF7000 4

  disable OTP
