The MMU is not used in ARM/U-boot, at least not on the i.MX31.
I was thinking there has to be a mechnism which defines the phystovirtual mapping table before the kernel starts running in the virtual space and the IO peripherals to access memory space/registers. Redboot does the same, hence i thought u-boot must be doing it somewhere.
That's done by the kernel in the early startup after decompressing.
