Greg Ungerer fa6667fe0f m68knommu: add smc91x support for ColdFire NETtel boards
The ColdFire based NETtel boards use the SMC9196 ethernet devices.

The init code is taken strait out of arch/m68k/include/asm/mcfsmc.h,

Steven King 91d6041721 m68knommu: Coldfire QSPI platform support
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.

john stultz 355e8e8d1b m68knommu: fix invalid flags on coldfire pit clocksource
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).

Lennart Sorensen 588baeac38 m68knommu: add uboot commandline argument passing support
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.

Greg Ungerer cd3dd4068d m68knommu: use general interrupt controller for ColdFire 520x family
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.
