    Dajun,

    MMU is disabled in u-boot. There are cases where its enabled in u-boot, but even then it will be one-to-one mapping in page table. I am assuming that you are referring to kernel image being able to run from any address. There are relocation happening to kernel image to the actual address, one from u-boot or from kernel's start code. Hope I could clarify your query.
