* sh: TLB miss fast-path optimizations.Stuart Menefy2006-12-065-114/+201
| | | | | | | | Handle simple TLB miss faults which can be resolved completely from the page table in assembler. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: R7780RP push-switch support.Paul Mundt2006-12-062-1/+125
| | | | | | | This adds simple push-switch support for the RDBRP-1/RDBREVRP-1 debug boards found on the R7780RP-1. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: generic push-switch framework.Paul Mundt2006-12-064-1/+150
| | | | | | | | | | This adds support for a generic push switch framework. Adaptable for various switches, including GPIO switches and the push switches commonly found on Renesas debug boards. This allows switch states to be trivially reported through sysfs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pmd rework.Stuart Menefy2006-12-062-17/+49
| | | | | | | | | Remove extra bits from the pmd structure and store a kernel logical address rather than a physical address. This allows it to be directly dereferenced. Another piece of wierdness inherited from x86. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Use MMU.TTB register as pointer to current pgd.Stuart Menefy2006-12-061-10/+8
| | | | | | | | | Add TTB accessor functions and give it a sensible default value. We will use this later for optimizing the fault path. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Set up correct siginfo structures for page faults.Stuart Menefy2006-12-063-49/+58
| | | | | | | | Remove the previous saving of fault codes into the thread_struct as they are never used, and appeared to be inherited from x86. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: gcc4 support.Stuart Menefy2006-12-068-64/+78
| | | | | | | | | | | | This fixes up the kernel for gcc4. The existing exception handlers needed some wrapping for pt_regs access, acessing the registers via a RELOC_HIDE() pointer. The strcpy() issues popped up here too, so add -ffreestanding and kill off the symbol export. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Explicit endian selection support.Paul Mundt2006-12-062-14/+21
| | | | | | | | | | | | Previously big endian was simply assumed if little endian was not set, which led to some cflags ordering issues. There's not much point to not having a big endian option, so shove one in a choice and wire it up in the Makefile. This lets us clean up some of the cflags ordering while we're at it.

* sh: p3map_sem sem2mutex conversion.Paul Mundt2006-12-062-26/+11
| | | | | | Simple sem2mutex conversion for the p3map semaphores. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Preliminary support for SH-X2 MMU.Paul Mundt2006-12-064-17/+52
| | | | | | | | | | | | | | | | | | | This adds some preliminary support for the SH-X2 MMU, used by newer SH-4A parts (particularly SH7785). This MMU implements a 'compat' mode with SH-X MMUs and an 'extended' mode for SH-X2 extended features. Extended features include additional page sizes (8kB, 4MB, 64MB), as well as the addition of page execute permissions. The extended mode attributes are placed in a second data array, which requires us to switch to 64-bit PTEs when in X2 mode. With the addition of the exec perms, we also overhaul the mmap prots somewhat, now that it's possible to handle them more intelligently. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Hook SH7785 in to the build system.Paul Mundt2006-12-062-1/+7
| | | | | | Simple 7785 placeholders to start hooking up other bits of code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Drop CPU subtype IRQ headers.Paul Mundt2006-12-065-31/+51
| | | | | | | | | | | | | This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes. This quickly got to be an unmaintainable mess, made even more evident by the subtle breakage introduced by the SH-2 and SH-2A changes. Now that subtypes are able to register IRQ maps directly, just rip all of the headers out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Configurable timer IRQ.Paul Mundt2006-12-065-4/+11
| | | | | | | | | All of the various CPU subtypes currently hardcode TIMER_IRQ, switch this to a config option in the few places we need this. This allows further removal of hardcoded IRQ headers.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fixup entry-common path breakage for SH-3.Paul Mundt2006-12-061-1/+1

* sh: Exception vector rework and SH-2/SH-2A support.Yoshinori Sato2006-12-067-332/+767
| | | | | | | | | This splits out common bits from the existing exception handler for use between SH-2/SH-2A and SH-3/4, and adds support for the SH-2/2A exceptions. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Wire up division and address error exceptions on SH-2A.Yoshinori Sato2006-12-061-9/+79
| | | | | | | | SH-2A has special division hardware as opposed to a full-fledged FPU, wire up the exception handlers for this. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add support for SH7206 and SH7619 CPU subtypes.Yoshinori Sato2006-12-0625-53/+1000

| | | | | | | | | | | | | | | | | | | | | | | | | | | | N32 SysV IPC system calls should use 32-bit compatible code. arch/mips/kernel/linux32.c have similar compatible code for O32, but ipc/compat.c seems more complete. We can use it for both N32 and O32.
