This breaks several board, I bisected imx8mm-cl-iot-gate because those 
boards don't define boot_mode_apply:

+arch/arm/mach-imx/cmd_bmode.c:86: undefined reference to `boot_mode_apply'
+make[1]: *** [Makefile:1765: u-boot] Error 139

I cannot apply this, please check and repost, thanks.

Best regards,
Stefano
