Regarding the selinux authority problem, during the booting process, before the kernel start up, you need to press any key of your keyboard, after that, you can change the "bootargs". The "bootargs" can vary depending of your setup.
This is an example of how to boot whit a single LDVS display:
U-Boot > setenv bootcmd boota mmc0
U-Boot > setenv bootargs console=ttymxc0,115200 init=/init androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale androidboot.selinux=disabled
androidboot.dm_verity=disabled
U-Boot > saveenv
I hope this can help you.
Best Regards,
Diego.
