* sh: Kill off the remnants of the old timer code.Paul Mundt2009-05-121-1/+1
| | | | | | | | Now with all of the TMU users moved over to the new TMU driver, and the old TMU driver killed off, the left-over infrastructure can go along with it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Drop dead rules from arch/sh/kernel/Makefile_64.Paul Mundt2009-05-081-3/+0Star
| | | | | | | | Several of these options are specific to the SHcompact ISA and will need to be rewritten for SHmedia if they are to be supported at all. Drop the impossible rules for now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Rename arch/sh/kernel/time_32.c to arch/sh/kernel/time.c.Paul Mundt2009-05-081-1/+1
| | | | | | | This is now fully generic, and used both by _32 and _64 variants. Rename it accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Finish the sh64 migration off of ARCH_USES_GETTIMEOFFSET.Paul Mundt2009-05-081-1/+1
| | | | | | | | This adds sh_tmu support to the SH-5 subtypes, which subsequently allows us to kill off time_64.c and use the now generic time_32.c. As a bonus, SH-5 now supports highres timers and tickless for the first time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Move dummy clockevents broadcast timer to its new home.Paul Mundt2009-05-031-0/+2
| | | | | | | | The old arch/sh/kernel/timers/ directly will be going away completely once the rest of the TMU users are migrated, so move the dummy broadcast driver up a level in preparation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off cf-enabler with extreme prejudice.Paul Mundt2008-12-221-1/+0Star
| | | | | | | | | | | | | | | Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off remaining CONFIG_SH_KGDB bits.Paul Mundt2008-12-221-1/+0Star
| | | | | | | Now that we use the generic stub, kill off all of the left over references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: move the hp6xx pm codeMagnus Damm2008-12-221-1/+0Star
| | | | | | | | | | 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>

* sh: Only build in gpio.o when CONFIG_GENERIC_GPIO is selected.Paul Mundt2008-10-201-1/+2
| | | | | | | | | The pinmux management is tied in to this code, while it is presently only used by platforms that select GENERIC_GPIO. The asm/gpio.h definitions are not referenced when GENERIC_GPIO is disabled, resulting in a build failure for all of the platforms that don't select it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: GPIO and pinmux base codeMagnus Damm2008-10-201-1/+1
| | | | | | | | This patch adds gpio code together with the pinmux table parser. In the future we should optimize this and switch back to gpiolib. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Tidy up ELF core dumps.Paul Mundt2008-09-121-1/+0Star
| | | | | | | | | | These have been using overrides for ELF_CORE_COPY_TASK_REGS and ELF_CORE_COPY_FPREGS while the generic versions can be used instead. Presently the pt_regs are also duplicated across elf_core_copy_regs() and elf_core_copy_task_regs(), this switches to simply copying out through elf_core_copy_regs() instead.

* Generic semaphore implementationMatthew Wilcox2008-04-171-1/+1
| | | | | | | | | | | Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary.

* sh: trapped io support V2Magnus Damm2008-02-141-0/+1
| | | | | | | | | | | | | | | | | | | The idea is that we want to get rid of the in/out/readb/writeb callbacks from the machvec and replace that with simple inline read and write operations to memory. Fast and simple for most hardware devices (think pci). Some devices require special treatment though - like 16-bit only CF devices - so we need to have some method to hook in callbacks. This patch makes it possible to add a per-device trap generating filter. This way we can get maximum performance of sane hardware - which doesn't need this filter - and crappy hardware works but gets punished by a performance hit. V2 changes things around a bit and replaces io access callbacks with a simple minimum_bus_width value. In the future we can add stride as well.
