* sh: oprofile: Refactor common setup code for multiple driver support.Paul Mundt2008-12-22
| | | | | | | | This re-implements the old op_model_null code in to something more generic, where multiple drivers, backtrace, etc. can all be interfaced. Based largely on arch/mips/oprofile/common.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Enable GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH machinesMatt Fleming2008-12-22
| | | | | | | | | After the recent changes to switch SuperH board support over to irq_chip it is now possible to set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Convert Cayman boards from hw_interrupt_type to irq_chipMatt Fleming2008-12-22
| | | | | | | | | I've been unable to even compile-test this change because I don't have an sh5 toolchain. All uses of hw_interrupt_type for SuperH boards have now been converted to use irq_chip. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Convert Dreamcast support from hw_interrupt_type to irq_chipMatt Fleming2008-12-22
| | | | | | | | | | | | | | | Switch the dreamcast IRQ code over to the irq_chip way of doing things, so that we can set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards. Also, whilst I'm here change some things to make checkpatch.pl happy: - Indent with tabs, not with spaces - Include <linux/io.h>, not <asm/io.h> - Fix the multi-line comment style - Fix some typos in the comments Tested-by: Adrian McMenamin <adrian@newgolddream.dyndns.info> Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Convert SystemH board support from hw_interrupt_type to irq_chipMatt Fleming2008-12-22
| | | | | | | ... as part of the hw_interrupt_type to irq_chip crusade. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Convert Microdev boards from hw_interrupt_type to irq_chipMatt Fleming2008-12-22
| | | | | | | This is part of the SH move to irq_chip. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Provide sdivsi3/udivsi3/udivdi3 for sh64, kill off libgcc linking.Paul Mundt2008-12-22
| | | | | | | This moves in the necessary libgcc bits and kills off the libgcc linking for sh64 kernels as well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* fb: SH-5 uses __raw I/O accessors now also, drop the special casing.Paul Mundt2008-12-22
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add SH-5 optimized memcpy()/memset()/strcpy()/strlen().Paul Mundt2008-12-22
| | | | | | Adopted from the uClibc optimized string versions. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off remaining CONFIG_SH_KGDB bits.Paul Mundt2008-12-22
| | | | | | | Now that we use the generic stub, kill off all of the left over references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: sh-sci: Implement CONSOLE_POLL support and kill off old kgdb console.Paul Mundt2008-12-22
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Generic kgdb stub support.Paul Mundt2008-12-22
| | | | | | | | This migrates from the old bitrotted kgdb stub implementation and moves to the generic stub. In the process support for SH-2/SH-2A is also added, which the old stub never provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Enable HAVE_ARCH_TRACEHOOK for all SH, now that SH-5 supports it too.Paul Mundt2008-12-22
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Provide linux/regset.h interface for SH-5.Paul Mundt2008-12-22
| | | | | | Plugs in general and FPU regsets. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Provide asm/syscall.h for SH-5.Paul Mundt2008-12-22
| | | | | | This provides the asm/syscall.h implementation for sh64 parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Handle cases where setup{_rt,}_frame() fail on SH-5 signal delivery.Paul Mundt2008-12-22
| | | | | | | | Presently these cases are not handled properly due to the return value not being passed back. This needs to be correct to get proper behaviour out of things like the tracehook signal notifier, amongst others. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up syscall_get_nr() comment in syscall_32.h.Paul Mundt2008-12-22
| | | | | | Residual copy-and-paste damage, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up the cpu_asid() return value on nommu.Paul Mundt2008-12-22
| | | | | | This ought to be unsigned long, rather than defaulting to int. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Convert sh64 /proc/asids to debugfs and generic sh.Paul Mundt2008-12-22
| | | | | | | | | | | This converts the sh64 /proc/asids entry to debugfs and enables it for all SH parts that have debugfs enabled. On MMU systems this can be used to determine which processes are using which ASIDs which in turn can be used for finer grained cache tag analysis. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off sh64's unused alloc/free_task_struct() definitions.Paul Mundt2008-12-22
| | | | | | | | These were left over from some time ago, sh64 never got around to defining __HAVE_ARCH_TASK_STRUCT_ALLOCATOR during the conversion, and it has no need to. Kill these off and use the generic versions instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: mach-migor: Kill off unused Migo-R machvec.Paul Mundt2008-12-22
| | | | | | | | This kills off the special Migo-R machvec, as nothing is using it. By default this will switch to using the generic machvec, which provides the same functionality. This saves us a bit of space in the machvec section. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: add ov772x reset delay on Migo-RMagnus Damm2008-12-22
| | | | | | | Add reset delay for the ov772x device on Migo-R. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Drop the special qemu defconfig.Paul Mundt2008-12-22
| | | | | | | QEMU can now use rts7751r2dplus_defconfig directly, there is no more need for a neutered defconfig. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Delete unnecessary mov in the interrupt exception entry point.Aoi Shinkai2008-12-22
| | | | | | | | | The INTEVT read at interrupt exception entry is uneccessary, as the read is deferred until we are ready to enter do_IRQ(). The kgdb nmi path still requires it, so move it there. Signed-off-by: Aoi Shinkai <shinkoi2005@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Disable -Werror for arch/sh/oprofile/.Paul Mundt2008-12-22
| | | | | | | drivers/oprofile/ objects have proven to be problematic in this regard, so simply disable -Werror for now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add plain udivsi3 (not _i4*) for gcc-4.1 and lower.Takashi YOSHII2008-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We chan't share code for udivsi3 and udivsi3_i4, because they have a different clobber list. Copy udivsi3 from gcc-4.1.2. As shown in arch/sh/lib/udivsi3.S (and -Os.S), .global __udivsi3_i4i .global __udivsi3_i4 .global __udivsi3 __udivsi3_i4i: ... Three symbols are sharing one code, which is actually udivsi3_i4i. But, this results unwanted code with gcc 4.1. In gcc, these three are treated as pseudo instructions that have their own clobber list apart from the usual calling convention. According to sh's machine description. The clobber list is as follows: - udivsi3_i4i : t,r1,pr,mach,macl - udivsi3_i4 : t,r0,r1,r4,r5,pr,dr0,dr2,dr4 - udivsi3 : t,r4,pr The caller of udivsi3 will be left with a broken r1 and mac*. gcc-4.1.x and older(at least to 3.4) generate udivsi3. ST's gcc-4.1.1 seems to be OK because it has _i4i. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Fix up the SH-4A mutex fastpath semantics.Paul Mundt2008-12-22
| | | | | | | | | This fixes up the __mutex_fastpath_xxx() routines to match the semantics noted in the comment. Previously these were looping rather than doing a single-pass, which is counter-intuitive, as the slow path takes care of the looping for us in the event of contention.

| | | | | | | | | Remove out-of-date se7343 ioport code including some old support for unknown-ne2000-pcmcia-card, cf-over-pcmcia and a mysterical smc91x that once must have been on a special daughterboard. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Switch HD64461 from hw_interrupt_type to irq_chipMatt Fleming2008-12-22
| | | | | | | | | | | | | | Use struct irq_chip for the interrupt handler for the HD64461. Also convert some in{b,w} and out{b,w} calls to the equivalent __raw_* calls. Include <linux/io.h> and not <asm/io.h> to stop checkpatch.pl complaining. This change should now allow machines with HD64461 to define GENERIC_HARDIRQS_NO__DO_IRQ.
