2011-12-24m68k: print memory layout info in boot logGreg Ungerer
Output a table of the kernel memory regions at boot time. This is taken directly from the ARM architecture code that does this. The table looks like this: Virtual kernel memory layout: vector : 0x00000000 - 0x00000400 ( 0 KiB) kmap : 0xd0000000 - 0xe0000000 ( 256 MiB) vmalloc : 0xc0000000 - 0xcfffffff ( 255 MiB) lowmem : 0x00000000 - 0x02000000 ( 32 MiB) .init : 0x00128000 - 0x00134000 ( 48 KiB) .text : 0x00020000 - 0x00118d54 ( 996 KiB) .data : 0x00118d60 - 0x00126000 ( 53 KiB) .bss : 0x00134000 - 0x001413e0 ( 53 KiB) This has been very useful while debugging the ColdFire virtual memory support code. But in general I think it is nice to know extacly where the kernel has layed everything out on boot. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-07-25m68knommu: correctly use trap_initGreg Ungerer
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.

2010-10-22m68k/m68knommu: merge the MMU and non-MMU traps.hGreg Ungerer
The MMU and non-MMU versions of traps.h are virtually identical, merge them into a single file. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2009-01-16m68k,m68knommu: merge header filesSam Ravnborg
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.
