LTIB BSP releases for the 547x/548x use the MMU.
If you look at the init code you'll see it initialized and then there is
MMU handling code to handle it. This code is also mostly common with
the 5445x.
There is an engineering team in China now handling linux/uclinux
development for coldfire chipsets. Those of us on the original team in
Utah were laid off earlier this year.

Hi Philippe,
I maintain LTIB (the tool). Generally speaking for MMUless
platforms I'd recommend using uClinux-dist. However if LTIB has the
exact platform you're interested in that may be helpful as it will
be known to work out of the box. The compiler used in LTIB should
work with uClinux-dist notwithstanding some gcc strictness issues
(depends on version). You may also find some of the patches to the
kernel that are not yet in mainstream may be useful. For platforms
with MMUs I'd recommend LTIB though (no surprise there).
The MCF5484 has a MMU, but linux-2.6.30 (even in uclinux-dist flavour)
does not seem to use it : I grep'ped for mmubar in the whole source tree
without result.
Does the ltib-provided kernel use the mmu ? And if that's the case,
is there an ongoing effort to merge those mmu patches in the uclinux-
or Linus' kernel tree ?
I will happily take patches for the uClinux-dist :-)
I try to track mainline kernels reasonably closely otherwise.
I get very few patches from Freescale for new ColdFire support
(Matt Wadell being the only exception to that I can recall).
Many years ago Motorola sent me every new CPU dev board, and
I could keep them up to date. Freescale hasn't done that in recent
years though.

Greg
