Is it OK to tie unused EIM GPIO boot pins directly to supplies?

I'm currently designing an i.MX6DL-based design that isn't using any of the GPIO BOOT_CFG signals for anything other than boot configuration at startup. Can I tie these directly to GND or NVCC_EIM? I'd like to avoid having to design in a bunch of unnecessary pull resistors. Will this affect power consumption of the design?

Hi Jay

yes it is allowed if design provides that voltage on these pins will not exceed power

supply of these pins, for example during power-up.
