Greg Ungerer 8a415c4be5 m68knommu: remove unused ColdFire 5282 register definitions
There is a bunch of old unused and ugly register definitions in the ColdFire
5282 header. Remove them.

Steven King bdee4e26ba m68knommu: use MCF_IRQ_PIT1 instead of MCFINT_VECBASE + MCFINT_PIT1
use MCF_IRQ_PIT1 instead of MCFINT_VECBASE + MCFINT_PIT1 so we can support
those parts that have the pit1 interrupt on other than the first interrupt
controller.

Greg Ungerer c222f5f41f m68knommu: switch to GPIO init macros in ColdFire 528x init code
Modify the GPIO setup table to use the mcfgpio.h macros for table init.
Simplifies code and reduces line count significantly.

We also need to rename some of the GPIO registers to be consistent with
all other ColdFire parts (we can't use the new GPIO macros otherwise).

Greg Ungerer 3b2039b266 m68knommu: make 528x QSPI platform addressing consistent
If we make all QSPI (SPI protocol) addressing consistent across all ColdFire
family members then we will be able to remove the duplicated plaform data
and code and use a single setup for all.

So modify the ColdFire 528x QSPI addressing so that:

. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used
. move chip select definitions (CS) to appropriate header

Greg Ungerer ce3de78a1c m68knommu: remove ColdFire CLOCK_DIV config option
The reality is that you do not need the abiltity to configure the
clock divider for ColdFire CPUs. It is a fixed ratio on any given
ColdFire family member. It is not the same for all ColdFire parts,
but it is always the same in a model range. So hard define the divider
for each supported ColdFire CPU type and remove the Kconfig option.

Greg Ungerer 6a92e1982d m68knommu: clean up use of MBAR for DRAM registers on ColdFire start
In some of the RAM size autodetection code on ColdFire CPU startup
we reference DRAM registers relative to the MBAR register. Not all of
the supported ColdFire CPUs have an MBAR, and currently this works
because we fake an MBAR address on those registers. In an effort to
clean this up, and eventually remove the fake MBAR setting make the
DRAM register address definitions actually contain the MBAR (or IPSBAR
as appropriate) value as required.

Greg Ungerer babc08b7e9 m68knommu: move ColdFire DMA register addresses to per-cpu headers
The base addresses of the ColdFire DMA unit registers belong with
all the other address definitions in the per-cpu headers. The current
definitions assume they are relative to an MBAR register. Not all
ColdFire CPUs have an MBAR register. A clean address define can only
be acheived in the per-cpu headers along with all the other chips
peripheral base addresses.

Greg Ungerer a0ba4332a2 m68knommu: remove use of MBAR value for ColdFire 528x peripheral addressing
The ColdFire 528x family of CPUs does not have an MBAR register, so don't
define its peripheral addresses relative to one. Its internal peripherals
are relative to the IPSBAR register, so make sure to use that.

Greg Ungerer f317c71a2f m68knommu: move ColdFire PIT timer base addresses
The PIT hardware timer module used in some ColdFire CPU's is not always
addressed relative to an IPSBAR register. Parts like the ColdFire 5207 and
5208 have fixed peripheral addresses. So lets not define the register
addresses of the PIT relative to an IPSBAR definition. Move the base
address definitions into the per-part headers. This is a lot more consistent
since all the other peripheral base addresses are defined in the per-part
header files already.

Greg Ungerer 254eef7464 m68knommu: remove kludge seting of MCF_IPSBAR for ColdFire 54xx
The ColdFire 54xx family shares the same interrupt controller used
on the 523x, 527x and 528x ColdFire parts, but it isn't offset
relative to the IPSBAR register. The 54xx doesn't have an IPSBAR
register.

By including the base address of the peripheral registers in the register
definitions (MCFICM_INTC0 and MCFICM_INTC1 in this case) we can avoid
having to define a fake IPSBAR for the 54xx. And this makes the register
address definitions of these more consistent, the majority of the other
register address defines include the peripheral base address already.

Greg Ungerer 57015421d3 m68knommu: move UART addressing to part specific includes
The ColdFire UART base addresses varies between the different ColdFire
family members. Instead of keeping the base addresses with the UART
definitions keep them with the other addresses definitions for each
ColdFire part.

The motivation for this move is so that when we add new ColdFire
part definitions, they are all in a single file (and we shouldn't
normally need to modify the UART definitions in mcfuart.h at all).

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

use other gpios as needed.

Sam Ravnborg 49148020bc m68k,m68knommu: merge header files
Merge header files for m68k and m68knommu to the single location:

    arch/m68k/include/asm

The majority of this patch was the result of the
script that is included in the changelog below.

The script was originally written by Arnd Bergman and
exten by me to cover a few more files.

When the header files differed the script uses the following:

The original m68k file is named <file>_mm.h  [mm for memory manager]
The m68knommu file is named <file>_no.h [no for no memory manager]

The files uses the following include guard:

This include gaurd works as the m68knommu toolchain set
the __uClinux__ symbol - so this should work in userspace too.

Merging the header files for m68k and m68knommu exposes the
(unexpected?) ABI differences thus it is easier to actually
identify these and thus to fix them.

The commit has been build tested with both a m68k and
a m68knommu toolchain - with success.

The commit has also been tested with "make headers_check"
and this patch fixes make headers_check for m68knommu.
