2008-12-22sh: Generic kgdb stub support.Paul Mundt
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>
2008-12-22sh: Enable HAVE_ARCH_TRACEHOOK for all SH, now that SH-5 supports it too.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Provide linux/regset.h interface for SH-5.Paul Mundt
Plugs in general and FPU regsets. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Provide asm/syscall.h for SH-5.Paul Mundt
This provides the asm/syscall.h implementation for sh64 parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Handle cases where setup{_rt,}_frame() fail on SH-5 signal delivery.Paul Mundt
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>
2008-12-22sh: Fix up syscall_get_nr() comment in syscall_32.h.Paul Mundt
Residual copy-and-paste damage, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Fix up the cpu_asid() return value on nommu.Paul Mundt
This ought to be unsigned long, rather than defaulting to int. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Convert sh64 /proc/asids to debugfs and generic sh.Paul Mundt
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>
2008-12-22sh: Kill off sh64's unused alloc/free_task_struct() definitions.Paul Mundt
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>
2008-12-22sh: mach-migor: Kill off unused Migo-R machvec.Paul Mundt
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>
2008-12-22sh: add ov772x reset delay on Migo-RMagnus Damm
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>
2008-12-22sh: Drop the special qemu defconfig.Paul Mundt
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>
2008-12-22sh: Delete unnecessary mov in the interrupt exception entry point.Aoi Shinkai
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>

2008-12-22sh: Enable leds-gpio in rsk7203 defconfig.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Consolidate rsk7203/7201 in to a new mach-rsk.Paul Mundt
RSK+ platforms have quite a few characteristics in common, so roll them together in to a shiny new RSK mach-type. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Provide ftrace_make_call()/ftrace_make_nop().Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Disable -Werror for arch/sh/oprofile/.Paul Mundt
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>
2008-12-22sh: Add plain udivsi3 (not _i4*) for gcc-4.1 and lower.Takashi YOSHII
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>

Fix incorrect use of loose in c-checksum.c It should be 'lose', not 'loose'. Signed-off-by: Nick Andrew <nick@nick-andrew.net> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Fix up the SH-4A mutex fastpath semantics.Paul Mundt
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.

2008-12-22sh: move the hp6xx pm codeMagnus Damm
Move the not-so-generic pm code from arch/sh/kernel/pm.c to the platform directory together with the rest of the hp6xx pm code. This is done to let non-hp6xx platforms enable CONFIG_PM. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: Switch HD64461 from hw_interrupt_type to irq_chipMatt Fleming
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.

2008-12-22sh: do not latency trace idle.Paul Mundt
Description snipped from Steven Rostedt's PPC patch: When idle is called, interrupts are blocked, but the idle function will still wake up on an interrupt. The problem is that the interrupt disabled latency tracer will take this call to idle as a latency. This patch disables the latency tracing when going into idle.

2008-12-22sh: Add a simple code dumper for SUPERH32 show_regs().Paul Mundt
This implements a simple show_code() that is in turn plugged in to show_regs() to provide minimal code dumping at the end of the trace. Built on top of a simple instruction disassembler derived from the binutils opcode table. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Add a few more branch types to the branch emulator.Paul Mundt

2008-12-22sh: Re-add support for best fit ISA tuning if none is available.Paul Mundt
This was removed in the libgcc integration, but there are still some compilers that need this. We also relax the rules on the ISA tuning in the cases where there are no matches for the CPU tuning and adopt the -any default, which matches the intent of the isa-y target list. This compensates for mismatches where binutils supports a wide array of targets whilst the compiler is much more restricted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: Provide optimized unaligned loads on SH-4A.Paul Mundt
This adds support for unaligned loads on SH-4A, using the SH-4A's neutered movua.l instruction. As movua.l is r0-inspired, stores are still handled through the packed struct. Based on asm-generic/unaligned.h by Harvey Harrison. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: P4 ioremap pass-throughMagnus Damm
This patch adds a pass-through case when ioremapping P4 addresses. Addresses passed to ioremap() should be physical addresses, so the best option is usually to convert the virtual address to a physical address before calling ioremap. This will give you a virtual address in P2 which matches the physical address and this works well for most internal hardware blocks on the SuperH architecture. However, some hardware blocks must be accessed through P4. Converting the P4 address to a physical and then back to a P2 does not work. One example of this is the sh7722 TMU block, it must be accessed through P4. Without this patch P4 addresses will be mapped using PTEs which requires the page allocator to be up and running.
