2008-10-20sh: GPIO and pinmux base codeMagnus Damm
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>
2008-10-04sh: More I/O routine overhauling.Paul Mundt
This tidies up a lot of the PIO/MMIO split. No in-tree platforms were making use of the MMIO overloading through the machvec (nor have any of them been in some time), so we just kill all of that off. The ISA I/O routine wrapping remains unaffected, which remains the only special casing outside of the iomap API that boards need to think about. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-10-01video: sh_mobile_lcdcfb: Support HAVE_CLK=n configurations.Paul Mundt
This provides a workaround for users of sh_mobile_lcdcfb that don't define HAVE_CLK and have otherwise sane clock initialization. At the same time, move the sh_mobile_lcdc.h header to include/video/. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-10-01sh: Move the shared INTC code out to drivers/sh/Paul Mundt
The INTC code will be re-used across different architectures, so move this out to drivers/sh/ and include/linux/sh_intc.h respectively. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-10-01sh: Fix up the __raw_read/writeX() definitions.Paul Mundt
These were doing largely bogus things and using the wrong typing for the address. Bring these in line with the ARM definitions. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-29sh: sh_ksyms_64 needs __strncpy_from_user() definition.Paul Mundt

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-21sh: Add FPU registers to regset interface.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-21sh: Add missing asm/ftrace.h.Paul Mundt
This was missed with the ftrace support commit.. check it in now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-21sh: Move lookup_exception_vector() out to asm/system_32.h.Paul Mundt
There are other places where we want to have access to the trap/exception number, so move out the lookup_exception_vector() helper. While we're at it, refactor it slightly to return the vector instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-21sh: Add a few more definitions to asm/sizes.h.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-21sh: Copy in asm/sizes.h helper from ARM.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-20sh: Support kernel stacks smaller than a page.Paul Mundt
This follows the powerpc commit f6a616800e68b61807d0f7bb0d5dc70665ef8046 '[POWERPC] Fix kernel stack allocation alignment'. SH has traditionally forced the thread order to be relative to the page size, so there were never any situations where the same bug was triggered by slub. Regardless, the usage of > 8kB stacks for the larger page sizes is overkill, so we switch to using slab allocations there, as per the powerpc change. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-17sh: Fix up headers_check regression.Paul Mundt
linux/mmzone.h isn't exported, kill it off from asm/setup.h and simply deal with it in the places that have a dependency instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-17sh: Consolidate struct sh_cpuinfo definitions across _32/_64 split.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-12sh: Tidy up ELF core dumps.Paul Mundt
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.

Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control page is used for not only code on some platform. For example in kexec jump, it is used for data and stack too.

2008-08-04add addrespace definition for sh2a.Takashi Yoshii
Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h), but, I'd like to add sh2a specific file here, because 1. the values defined there are not suitable for sh2a. 2. I don't think there is "common" definition for these values. Values are chosen by consideration of followings... P1 is 0. perhaps no question. P2 is from hardware manual, which says no-cache area starts at 20000000. It means that P? space size=20000000. P3 is P2+size since asm/ptrace.h uses P3 as a end of P2. P4 is P3+size since asm/fixup.h uses P4 as a end of P3. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
