If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Marcin Wojtas commit db6ba9a5371f173489df126739d0a1c2a50f347b upstream. This commit adds missing configuration of MBUS windows access protection in mvneta_conf_mbus_windows function - a dedicated variable for that purpose remained there unused since v3.8 initial mvneta support. Because of that the register contents were inherited from the bootloader.
