I know imx8qm support system mmu because the imx8qm device tree has pointed out iommu and its physical address 514000000. But i would like to know whether imx8mq-evk support it.
uboot MMU in arch/arm/mach-imx/imx8m/soc.c
Do you mean mmu? MMU is for page table translate but System mmu(IOMMU) is for DMA or io. It's not different.
