Some more merging of MMU and non-MMU common files (specifically the arch process.c, ptrace and time.c). And a big cleanup of the massively duplicated ColdFire device definition code. Overall we remove about 2000 lines of code, and end up with a single set of platform device definitions for the serial ports, ethernet ports and QSPI ports common in most ColdFire SoCs. I expect you will get a merge conflict on arch/m68k/kernel/process.c, in cpu_idle(). It should be relatively strait forward to fixup."

| * m68k: merge the MMU and non-MMU versions of process.cGreg Ungerer2012-03-053-777/+377
| | | | | | | | | | | | | | | | | | | | The MMU and non-MMU varients of the m68k arch process.c code are pretty much the same. Only a few minor details differ between the two. The majority of the difference is to deal with having or wanting hardware FPU support. So merge them back into a single process.c file.

| * m68knommu: remove unused CONFIG_GENERIC_CMOS_UPDATE optionGreg Ungerer2012-03-051-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | The CONFIG_GENERIC_CMOS_UPDATE switch is always enabled for the non-MMU m68k case. But the underlying code to support it, update_persistent_clock(), doesn't end up doing anything on the currently supported non-MMU platforms. No platforms supply the necessary function support for writing back the RTC. So lets remove this option and support code. This also brings m68knommu in line with the m68k, which doesn't enabled this switch either. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
| * m68knommu: modify timer init code to make it consistent with m68k codeGreg Ungerer2012-03-052-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | With a few small changes we can make the m68knommu timer init code the same as the m68k code. By using the mach_sched_init function pointer and reworking the current timer initializers to keep track of the common m68k timer_interrupt() handler we end up with almost identical code for m68knommu. This will allow us to more easily merge the mmu and non-mmu m68k time.c in future patches. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

| | | | | | | | | | | | | | | | | | | | | | The read_persistent_clock() code is different on m68knommu, for really no reason. With a few changes to support function names and some code re-organization the code can be made the same. This will make it easier to merge the arch/m68k/kernel/time.c for m68k and m68knommu in a future patch. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

* | m68k: do not use m68k startup or interrupt code for ColdFire CPUsGreg Ungerer2011-12-301-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ColdFire CPUs have their own startup and interrupt code (in the platform/coldfire directory), and do not use the general m68k startup and interrupt code. In fact the use of the arch/m68k/kernel/head.o is not about CONFIG_MMU or not, it is really about the machine type we are compiling for. Modify the selection and use of head.o to be based on the machine type. Only select the local ints.o and vectors.o code if we are using the classic 68k CPU types (that use the conventional Morotola MMU or SUN3 MMU).

* | m68k: add ColdFire FPU support for the V4e ColdFire CPUsGreg Ungerer2011-12-303-66/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The V4e ColdFire CPU family also has an integrated FPU (as well as the MMU). So add code to support this hardware along side the existing m68k FPU code. The ColdFire FPU is of course different to all previous 68k FP units. It is close in operation to the 68060, but not completely compatible. The biggest issue to deal with is that the ColdFire FPU multi-move instructions are different. It does not support multi-moving the FP control registers, and the multi-move of the FP data registers uses a different instruction mnemonic.

This is not a difference based on the presence of a hardware MMU or not. Create a new config symbol to mark that a CPU type doesn't support the longer multiply/divide instructions. Use this then as a basis for using the fast 64bit based divide (in div64.h) and for linking in the extra libgcc functions that may be required (mulsi3, divsi3, etc).

Mostly the code currently uses the one inside of the thread_struct, only using the "task" pointer from the stack based one.
