Please don't add any new users of mxc_arch_reset_init_dt(). We now
have infrastructure to register a system-reset handler from the
watchdog driver, so please do that instead, and clean up the
existing users as well.

I believe someone recently posted a patch to derive the dma_zone_size
from device tree. Can yo try to find that and see if that will work
for you?
Can you explain what the reason is for needing a DMA zone?
