The NXP documentation declares the above signals as BOOT_CFG signals but no other information (function and reset status) is
currently given about them.
Basing on the Engicam test result we currently suggest leaving all these signals floating during reset status and
it's strongly
recommended to consult the NXP's documentation before starting the carrier board design.
WARNING:
The BOOT_CFG4 signals are used also to configure the boot from serial ROM, always refer to the NXP's
documentations to design and configure the listed BOOT_CFG signals of your own board
