The chips lists were in commit logs, but should also be in source files.
This way it is easier to choose the right source file for a not yet
supported Coldfire.

strace enabled is marked using the `flags' field of the `thread_info' struct.
68360 version of entry.S did test a wrong bit in a wrong structure
(task_struct).
68328 version of entry.S did test the right bit in the right structure,
but wrongly, because the `flags' field is 32 bit wide, while the used
assembler insn (btst) only accesses a 8 bit byte in memory.
Fix both using code already used in the coldfire version of entry.S

The ColdFire based NETtel boards use the SMC9196 ethernet devices.
Switch to using a platform setup for these parts using the smc91x driver.
The init code is taken strait out of arch/m68k/include/asm/mcfsmc.h,
just cleaned up a bit.

Since Grant has added the coldfire-qspi driver to next-spi, here is the
platform support for the parts that have qspi hardware. This sets up
gpio to do the spi chip select using the default chip select pins; it should
be trivial for boards that require different or additional spi chip selects to
use other gpios as needed.

The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource. Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.
This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource. This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).

This patch adds m68knommu support for getting the kernel command line
arguments from uboot, including the passing of an initrd image from uboot.
We use this on a 5270/5271 based board, and have used it on the 5271evb
development board. It is based on a patch found in the linux-2.6-denx
git tree, although that tree seems to have had lots of other changes
since which are not in the main Linus kernel. I believe this will work
on all coldfires, although other m68knommu might be missing the _init_sp
stuff in head.S as far as I can tell. I only have the coldfire to
test on.

The recent changes to the old ColdFire interrupt controller code means
we no longer need to manually unmask the timer interrupt. That is now

The older simple ColdFire interrupt controller has no one-to-one mapping
of interrupt numbers to bits in the interrupt mask register. Create a
mapping array that each ColdFire CPU type can populate with its available
interrupts and the bits that each use in the interrupt mask register.

The newer ColdFire 532x family of CPU's uses the old timer, but has a
newer interrupt controller. It doesn't need the special timer setup
that was required when using the older interrupt controller. Remove the
dead timer irq and level setting code, and define the hard coded vector.

The ColdFire "timers" clock setup can be simplified. There is really no
need for the flexible per-platform setup code. The clock interrupt can be
hard defined per CPU platform (in CPU include files). This makes the
actual timer code simpler.

Currently the code that supports setting the old style ColdFire interrupt
controller mask registers is macros in the include files of each of the
CPU types. Merge all these into a set of real masking functions in the
old Coldfire interrupt controller code proper. All the macros are basically
the same (excepting a register size difference on really early parts).

The old ColdFire CPU's (5206, 5307, 5407, 5249 etc) use a simple

The ColdFire 532x family of parts uses 2 of the same INTC interrupt
controlers used in the ColdFire 520x family. So modify the code to
support both parts. The extra code for the second INTC controler in
the case of the 520x is easily optimized away to nothing.

Create general interrupt controller code for the many ColdFire version 2
cores that use the two region INTC interrupt controller. This includes the
523x family, 5270, 5271, 5274, 5275, and the 528x families.
This code does proper masking and unmasking of interrupts. With this in
place some of the driver hacks in place to support ColdFire interrupts
can finally go away.

Create general interrupt controller code for the ColdFire 520x family,
that does proper masking and unmasking of interrupts. With this in
place some of the driver hacks in place to support ColdFire interrupts
can finally go away.
Within the ColdFire family there is a variety of different interrupt
controllers in use. Some are used on multiple parts, some on only one.
There is quite some differences in some varients, so much so that
common code for all ColdFire parts would be impossible.
This commit introduces code to support one of the newer interrupt
controllers in the ColdFire 5208 and 5207 parts. It has very simple
mask and unmask operations, so is one of the easiest to support.
