Well, !MMU and multiplatform _are_ exclusive in reality.  One of the
things we work around in multiplatform is the different physical
address space layouts of the platforms, particularly with where RAM
is located.  That's not possible in !MMU configurations.  A kernel
built to support every platform in multiplatform will not boot on
most of them.

So efforts to make !MMU work with multiplatform are IMHO rather
misguided.

!MMU makes sense with classifications of systems (like the Cortex-M*
based systems) but not everything.

Okay, seems you were referring to AUTO_ZRELADDR or if you had
something else in mind, please let me know.

The plan was to use Image instead of zImage. Here there are 2
platforms, Freescale's, oh no, NXP's, oh no no, Qualcomm's Vybrid
(vf610) and TI's Sitara siblings (am335x beagle & am437x). It was
thought that though changes might have to be made b/n them, at least
it might be easier using same defconfig, thus went by multi_v7.

Though have been able to build for !MMU, have not yet been successful
in seeing any activity on the console, probably will have to put
printascii() into service.
