Hi Greg,
The Freescale ColdFire M5441x system-on-chip parts have full paged MMU
hardware support. So far though we have only allowed them to be
configured for use in non-MMU mode.
All required kernel changes to support operation of the M5441x parts
with MMU enabled have been pushed into the kernel, so now we can allow
it to be configured and used with the MMU enabled.
I don't actually have any M5441x based hardware so I can't do any real
testing on this. The changes up to now were based on Yannick Gicquel
initial patches to support this. Is anybody out there able to test
this properly? I won't push this any further until we have some
confirmation that it all works as expected.

forgot some useful info on my test:
- i built a 4.12 kernel from mainline (just pulled git master) and tested
to boot properly as no-mmu
- i have those entries in my defconfig:
....
CONFIG_BINFMT_FLAT=y
CONFIG_BINFMT_ZFLAT=y
CONFIG_BINFMT_SHARED_FLAT=y
CONFIG_BINFMT_MISC=y
....
I can help on debug when back from holidays, in 3 weeks.
