Add an m68k/coldfire optimized memmove() function for the m68knommu arch.
This is the same function as used by m68k. Simple speed tests show this
is faster once buffers are larger than 4 bytes, and significantly faster
on much larger buffers (4 times faster above about 100 bytes).This also goes part of the way to fixing a regression caused by commit
ea61bc461d09e8d331a307916530aaae808c72a2 ("m68k/m68knommu: merge MMU and
non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is
the 68x328 and 68360 families). They currently have no memmove() fucntion
defined, since there was none in the m68knommu/lib functions.Signed-off-by: Greg Ungerer

The _TIF_WORK_MASK definition was removed in the clean up of MMU and
non-MMU arch/m68k/include/asm/thread_info*.h files (this was commit
cddafa3500fde4a07e5bf899ec97a04069f8f7ce, "merge MMU and non-MMU
thread_info.h").It didn't get cleaned out of the entry.S code for the 68328 and 68360
based platforms. And it was replaced by a hard coded constant mask for
coldfire platforms. There is currently no need to mask any of these bits,
so fix all uses (and former uses) to check for any non-zero value.Signed-off-by: Greg Ungerer

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.Reviewed-by: Ingo Molnar

The version 3 and version 4 ColdFire cache controllers support both
write-through and copy-back modes on the data cache. Allow for Kconfig
time configuration of this, and set the cache mode appropriately.Signed-off-by: Greg Ungerer
-
The newer version 2 ColdFire CPU cores support a configurable cache
arrangement. The cache memory can be used as all instruction cache, all
data cache, or split in half for both instruction and data caching.
Support this setup via a Kconfig time menu that allows a kernel builder
to choose the arrangement they want to use.Signed-off-by: Greg Ungerer
-
Currently the code to push cache lines is only available to version 4
cores. Version 3 cores may also need to use this if we support copy-
back caches on them. Move this code to make it more generic, and
useful for all version ColdFire cores.With this in place we can now have a single cache_flush_all() code
path that does all the right things on all version cores.Signed-off-by: Greg Ungerer
-
The cache control code for the ColdFire CPU's is a big ugly mess
of "#ifdef"ery liberally coated with bit constants. Clean it up.The cache controllers in the various ColdFire parts are actually quite
similar. Just differing in some bit flags and options supported. Using
the header defines now in place it is pretty easy to factor out the
small differences and use common setup and flush/invalidate code.I have preserved the cache setups as they where in the old code
(except where obviously wrong - like in the case of the 5249). Following
from this it should be easy now to extend the possible setups used on
the CACHE controllers that support split cacheing or copy-back or
write through options.Signed-off-by: Greg Ungerer

The instruction timings of the ColdFire 54xx family parts are
different to other version 4 parts (or version 2 or 3 parts for
that matter too).Move the instruction timing setting into the ColdFire part
specific headers, and set the 54xx value appropriately.Signed-off-by: Greg Ungerer

Move the ColdFire CPU names out of setup.c and into their repsective

The Freescale M547x family of ColdFire processors is very similar
to the M548x series. We use all the same support for it. Initially
all we need is a high level configuration option for it.Signed-off-by: Greg Ungerer
-
The ColdFire 547x family of processors is very similar to the ColdFire
548x series. Almost all of the support for them is the same. Make the
code supporting the 548x more gneric, so it will be capable of
supporting both families.For the most part this is a renaming excerise to make the support
code more obviously apply to both families.Signed-off-by: Greg Ungerer
