2011-10-24m68k/mac: Fix mac_irq_pending() for PSC MACE and SCCFinn Thain
Add missing return statement. The docs say that the level 4 PSC IRQs relate to MACE DMA and SCC. Since those drivers don't call mac_irq_pending() this patch has no affect. But it should be fixed all the same, since it can be useful for MACE debugging. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-10-24m68k/mac: Fix compiler warning in via_read_time()Finn Thain
The algorithm described in the comment compares two reads from the RTC but the code actually reads once and compares the result to an uninitialized value. This causes the compiler to warn, "last_result maybe used uninitialized". Make the code match the comment, fix the warning and perhaps improve reliability. Tested on a Quadra 700.

2011-10-18m68knommu: remove extern declarations of memory_start/memory_end from mm/initGreg Ungerer

2011-10-18m68k: merge the mmu and non-mmu traps.c filesGreg Ungerer
The code for handling traps in the non-mmu case is a subset of the mmu enabled case. Merge the non-mmu traps_no.c code back to a single traps.c. There is actually no code mmu specific here at all, and the processor specific code (for the more complex 68020/68030/68040/68060) is already proplerly conditionaly used. The format of console exception dump is a little different, but I don't think will cause any one problems, it is purely for debug purposes. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-10-18m68k: move hardware vector setting from traps.c to its own fileGreg Ungerer
Most of the trap.c code is general to all m68k arch members. But the code it currently contains to set the hardware vector table is quite specific to the 680x0 family. They can have the vector table at any address unlike other family members (which either support only a single fixed address, or a limited range of addresses). So lets move that code out to a new file, vectors.c. This will make sharing the rest of the trap.c code easier and cleaner. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-10-18m68k: merge mmu and non-mmu include/asm/entry.h filesGreg Ungerer
The changes in the mmu version of entry.h (entry_mm.h) and the non-mmu version (entry_no.h) are not about the presence or use of an MMU at all. The main changes are to support the ColdFire processors. The code for trap entry and exit for all types of 68k processor outside coldfire is the same. So merge the files back to a single entry.h and share the common 68k entry/exit code. Some changes are required for the non-mmu entry handlers to adopt the differing macros for system call and interrupt entry, but this is quite strait forward. The changes for the ColdFire remove a couple of instructions for the separate a7 register case, and are no worse for the older single a7 register case. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
