--- Comment #7 from david.welch at netronome dot com --- This is an armv6 not an armv7. So far I have not seen that the mmu or cache or branch prediction is required for proper operation of the core. I have so far not see this on other cores, but still working on that it is very much present on this core. I would rather not have to use the mmu as a kludge.
