juniskane opened a new pull request #4468:
URL: https://github.com/apache/incubator-nuttx/pull/4468

This change is also documented in app note AN5017 "Migrating between STM32L476xx/486xx and STM32L4+ Series microcontrollers" Rev 1 Table 9 page 20,
   
   ## Impact
   
   ## Testing
   Tested with STM32L4R5AI. The ST's production default option byte value 0xffeff8aa can be read.
