m68knommu: create and use a common M53xx ColdFire class of CPUs

2013-04-28T23:17:58+00:00

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. Signed-off-by: Greg Ungerer

m68knommu: merge ColdFire 5249 and 525x definitions

2012-12-05T00:51:21+00:00

The ColdFire 5249 and 525x family of SoCs are very similar. Most of the internals are the same, and are mapped the same. We can use a single set of peripheral definitions for all of them. So merge the current m5249sim.h and m525xsim.h definitions into a single file. The 5249 is now obsolete, and the 525x parts are current, so I have chosen to move everything into the existing m525xsim.h file. Signed-off-by: Greg Ungerer

m68knommu: Add support for the Coldfire m5441x.

2012-07-15T23:59:21+00:00

Add support for the Coldfire 5441x (54410/54415/54416/54417/54418). Currently we only support noMMU mode. It requires the PIT patch posted previously as it 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 apparently, the only difference a v4m (m5441x) and a v4e is the later has a FPU, which I don't think should matter to us in the kernel.

m68knommu: Add support for the Coldfire 5251/5253

m68knommu: make Coldfire 548x support more generic

2011-01-05T05:19:17+00:00

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

m68knommu: add basic mmu-less m548x support

2010-10-21T00:17:30+00:00

Add a very basic mmu-less support for coldfire m548x family. This is perhaps also valid for m547x family. The port comprises the serial, tick timer and reboot support. The gpio part compiles but is empty. This gives a functional albeit limited linux for the m548x coldfire family. This has been tested on a Freescale M548xEVB Lite board with a M5484 processor and the default dbug monitor. Signed-off-by: Philippe De Muyter Signed-off-by: Greg Ungerer

m68knommu: move ColdFire INTC definitions to new include file

2009-09-15T23:43:49+00:00

Create an mcfintc.h include file with the definitions for the old style ColdFire interrupt controller. They are only needed on CPU's that use this old controller - so isolate them on their own. Signed-off-by: Greg Ungerer

m68knommu: remove interrupt masking from ColdFire pit timer

2009-09-15T23:43:47+00:00

With proper interrupt controller code in place there is no need for devices like the timers to have custom interrupt masking code. Remove it (and the defines that go along with it). Signed-off-by: Greg Ungerer

m68k,m68knommu: merge header files

2009-01-16T11:58:10+00:00

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 _mm.h [mm for memory manager] The m68knommu file is named _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.
