[PATCH 2/2] imx9: scmi: soc: Add support for detecting primary/secondary bmode on MX95

[Fedor Ross]

Implement the 'getprisec' subcommand of 'bmode' command for i.MX95 by
reading out the ROM log events. This event is set by the BootROM if it
switched to the secondary copy due to primary copy being corrupted.
