NXP BBNSM (Battery-Backed Non-Secure Module) serves as non-volatile logic and storage for the system. it provides some similar functions like RTC and ON/OFF support as previous SNVS module found on legacy i.MX SoCs. The BBNSM is replacement of previous SNVS module, and more likely it will be used on all the future i.MX SoC or other SoCs from NXP. This patchset add the basic support for BBNSM that found on i.MX93.
