* m68k: Revive reporting of spurious interruptsGeert Uytterhoeven2011-07-254-8/+2
| | | | | | | | | | | | commit 2502b667ea835ee16685c74b2a0d89ba8afe117a ("Change the m68knommu irq handling to use the generic irq framework.") removed the reporting of spurious interrupts on nommu (68328 and 68360). Bring it back in a generic way, using "atomic_t irq_err_count", as that's what most of the other architectures are using.

* m68knommu: correctly use trap_initGreg Ungerer2011-07-257-19/+13
| | | | | | | | | | | | Currently trap_init() is an empty function for m68knommu. Instead the vectors are being setup as part of the IRQ initialization. This is inconsistent with m68k and other architectures. Change the local init_vectors() to be trap_init(), and init the vectors at the correct time during startup. This will help merge of m68k and m68knommu trap code in the furture. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: merge ColdFire 5206 and 5206e platform codeGreg Ungerer2011-07-254-194/+6
| | | | | | | | The ColdFire 5206 and 5206e CPU families are almost identical, we can easily merge the platform support code for them. All the differences are dealt with in the current include/asm/5206sim.h. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68k: merge MMU and non MMU versions of system.hGreg Ungerer2011-07-253-25/+25
| | | | | | | | | | | | | | The non-MMU m68k targets can use the same asm/system.h as the MMU targets. So switch the current system_mm.h to be system.h and remove system_no.h. The assembly support code for the non-MMU resume functions needs to be modified to match the now common switch_to() macro. Specifically this means correctly saving and restoring the status flags in the case of the ColdFire resume, and some reordering of the code to not use registers before they are saved or after they are restored.

* m68k: merge mmu and non-mmu versions of asm-offsets.cGreg Ungerer2011-05-243-11/+11
| | | | | | | | | It is strait forward to merge the mmu and non-mmu versions of asm-offstes.c. Some name changes are required for the preempt and thread_info.flags in the non-mmu entry.S assembler to make them consistent for both setups. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: remove un-needed exporting of COLDFIRE symbolsGreg Ungerer2011-05-241-0/+3
| | | | | | | | | | There is no reason most of the symbols enclosed in a conditional on CONFIG_COLDFIRE need to be exported. And they sure don't need to be doing it in m68k_ksyms_no.c. Move the dma symbols export (which are currently needed) to the definitions of those, and remove the rest of the exporting here. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

* m68k: merge m68k and m68knommu arch directoriesGreg Ungerer2011-03-2580-0/+14714
There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King <sfking@fdwdc.com>, which was originally written by Arnd Bergmann <arnd@arndb.de>. > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include <file>_mm.<ext> > #else > #include <file>_no.<ext> > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
