Jiang Liu d9e6ba5fed m68k/PCI: Remove redundant call of pci_bus_add_devices()
pci_scan_bus() has called pci_bus_add_devices() already, so remove the
redundant call of pci_bus_add_devices().  subsys_init() callbacks will be
invoked before device_init() callbacks, so it should be safe to remove the
redundant calls.

Greg Ungerer 2842e5b00e m68knommu: enable Timer on coldfire 532x
This patch enables the initial Timer on coldfire 532x systems.
Without this, the scheduler will not be triggered and the system hangs,
after all sequential code is executed. It should also apply on later kernel
versions.

Greg Ungerer e73cbe21ea m68knommu: make ColdFire M532x platform support more v3 generic
The M532x CPU platform support can be used on more ColdFire CPU families
than just the 532x types. So rename and reconfigure it to reflect that.
The ColdFire 537x family has virtualy identical internals to the 532x,
and so it will be able to share this code when we add support for them.

Greg Ungerer 6eac402783 m68knommu: create and use a common M53xx ColdFire class of CPUs
The current CONFIG_M532x support definitions are actually common to a larger
set of version 3 ColdFire CPU types. In the future we want to add support for
the 537x family. It is very similar to the 532x internally, and will be able
to use most of the same definitions.

Create a CONFIG_M53xx option that is enabled to support any of the common
532x and 537x CPU types. Convert the current users of CONFIG_M532x to use
CONFIG_M53xx instead.

Greg Ungerer 280ef31a00 m68knommu: modify clock code so it can be used by all ColdFire CPU types
The existing clk.c code for ColdFire CPUs has one set of functions to
support those CPU types that have selectable clocks (those with a PPMCR
register), and a duplicate simpler set for those with static clocks.

Modify the clk.c code so there is just one set of support functions. All
CPU types now define a list of clocks (in "struct clk"s), so we only need
a single set of clock functions.

So merge the current m5249sim.h and m525xsim.h definitions into a single

chosen to move everything into the existing m525xsim.h file.

uses the PIT instead of the dma timer as a clock source so we can get all that
GENERIC_CLOCKEVENTS goodness.  It also adds some simple clk definitions and
very simple minded power management.  The gpio code is tweeked and some
additional devices are added to devices.c.  The Makefile uses -mv4e as

Steven King eac5794994 m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate mcf_gpio_chips.
If we're not connecting external GPIO extenders via i2c or spi or whatever, we
probably don't need GPIOLIB.  If we provide an alternate implementation of
the GPIOLIB functions to use when only on-chip GPIO is needed, we can change
ARCH_REQUIRE_GPIOLIB to ARCH_WANTS_OPTIONAL_GPIOLIB so that GPIOLIB becomes
optional.

The downside is that in the GPIOLIB=n case, we lose all error checking done by
gpiolib, ie multiply allocating the gpio, free'ing gpio etc., so that the
only checking that can be done is if we reference a gpio on an external part.
Targets that need the extra error checking can still select GPIOLIB=y.

For the case where GPIOLIB=y, we can simplify the table of gpio chips to use a
single chip, eliminating the tables of chips in the 5xxx.c files.  The
original motivation for the definition of multiple chips was to match the way
many of the Coldfire variants defined their gpio as a spare array in memory.
However, all this really gains us is some error checking when we request a
gpio, gpiolib can check that it doesn't fall in one of the holes.  If thats
important, I think we can still come up with a better way of accomplishing
that.

Also in this patch is some general cleanup and reorganizing of the gpio header
files (I'm sure I must have had a reason why I sometimes used a prefix of
mcf_gpio and other times mcfgpio but for the life of me I can't think of it
now).

Geert Uytterhoeven dc0610518f m68k: Replace m68k-specific _[se]bss by generic __bss_{start,stop}
BSS_SECTION() provides the __bss_{start,stop} symbols, so there's no need
to wrap our own _[se]bss around it.

Greg Ungerer 19a1d332cc m68knommu: define a local devm_clk_get() function
Commit f4d40de39a ("net fec: do not depend
on grouped clocks") breaks compilation of the FEC driver for non iMX
platforms in linux-3.5-rc1. For example when compiling for ColdFire I get:

      LD      vmlinux
    drivers/built-in.o: In function `fec_probe':
    fec.c:(.devinit.text+0x1e0): undefined reference to `devm_clk_get'

Define a simple devm_clk_get() function for the m68knommu architecture.

Greg Ungerer 1b461d7631 m68knommu: fix 68360 local setting of timer interrupt handler
Compiling for 68360 based targets fails with:

    arch/m68k/platform/68360/config.c: In function ‘hw_tick’:
    arch/m68k/platform/68360/config.c:55:2: error: implicit declaration of function ‘arch_timer_interrupt’
    arch/m68k/platform/68360/config.c: At top level:
    arch/m68k/platform/68360/config.c:64:6: error: conflicting types for ‘hw_timer_init’
    arch/m68k/include/asm/machdep.h:36:13: note: previous declaration of ‘hw_timer_init’ was here

Changes made to hw_timer_init() didn't get updated in the 68328 timer code.
So process and call the "handler" arg that is now passed into that
hw_timer_init() function.
