* sh: Add plain udivsi3 (not _i4*) for gcc-4.1 and lower.Takashi YOSHII2008-12-224-629/+713
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Mundt2008-12-221-16/+21
| | | | | | | | | 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.

| | | | | | | | | | | | | | 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.

* sh: do not latency trace idle.Paul Mundt2008-12-221-0/+4
| | | | | | | | | | | | | 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.

| | | | | | | | | | 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>

* sh: Re-add support for best fit ISA tuning if none is available.Paul Mundt2008-12-221-5/+20
| | | | | | | | | | | 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>

* sh: Provide optimized unaligned loads on SH-4A.Paul Mundt2008-12-222-1/+264
| | | | | | | | | | 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>
* sh: P4 ioremap pass-throughMagnus Damm2008-12-224-12/+17
| | | | | | | | | | | | | | | | | | | | 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.
