2008-12-22sh: Kill off the unused SH_ALPHANUMERIC debug option.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Enable skipping of bss on debug platforms for sh32 also.Paul Mundt
This enables the same functionality that sh64 has for sh32. When running on simulated hardware or via remote memory via the debug interface, memory is gauranteed to be zero on boot already, and skipping the zeroing of BSS has measurable boot time benefits. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22doc: Update sh cpufreq documentation.Paul Mundt
The sh cpufreq driver is no longer limited to just the SH-3 and SH-4, update the documentation to reflect this fact accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mrshpc_setup_windows() needs to be inline.Paul Mundt
While no one should be including this file multiple times, flag it inline anyways just in case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22serial: sh-sci: sci_poll_get_char() is only used by CONFIG_CONSOLE_POLL.Paul Mundt
sci_poll_put_char() happens to also be used by the serial console, while sci_poll_get_char() is only used by CONFIG_CONSOLE_POLL. Add another gnarly ifdef to shut up the compiler. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off cf-enabler with extreme prejudice.Paul Mundt
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>
2008-12-22sh: Add a simple edosk7705_defconfig for build testing.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mach-edosk7705: Fix up edosk7705 so it all builds again.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mach-microdev: Split out the fdc37c93xapm initialization code.Paul Mundt
This makes the microdev code a bit more readable, and moves the setup for the SuperIO out on its own. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mach-sh03: Use __set_io_port_base(), kill off special ioport_map().Paul Mundt
This also fixes up a long-standing bug for this platform where the PIO base was set to a register offset, rather than the actual PIO offset itself. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mach-sh03: Move off of cf_enabler to pata_platform, as per landisk.Paul Mundt
This gets rid of the cf enabler use on mach-sh03 and switches to use pata_platform with the proper address directly. cf_enabler is subsequently disabled for mach-sh03. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: board-shmin: Convert shmin to use __set_io_port_base().Paul Mundt
Drop the special mv_ioport_map() implementation, as this can simply use __set_io_port_base() directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off dead mv_init_pci() from machvec.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Simplify kernel_thread_helper() for sh32.Paul Mundt
This can use the same implementation as sh64, the generated assembly is the same between the new and old version, so there is not much point in leaving it open coded in inline assembly. This is preparatory work for future consolidation of the _32/_64 variants. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off mv_heartbeat() from the machvec.Paul Mundt
Nothing is using this any more, so get rid of it before anyone gets the bright idea to start using it again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off the cayman and microdev special heartbeat code.Paul Mundt
These can use the generic code instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off sh_bios_in_gdb_mode().Paul Mundt
With the reworked kgdb support, we always detach and reinitialize the stub. This was mostly a feature for handoffs between sh-ipl+g and the kgdb stub, but virtually no sh-ipl+g versions ever had this working right in the first place. Given that the sh-ipl+g stubs in general use today don't even support the GDB stub, and we have already killed off the special casing in the sh-sci serial driver, kill off this now unused symbol too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: oprofile: Convert op_model_sh7750 to new common interface.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: oprofile: Backtrace support.Dave Peverley
This patch improves the oprofile support on sh and adds backtrace support. Signed-off-by: Dave Peverley <dpeverley@mpc-data.co.uk> Signed-off-by: Chris Smith <chris.smith@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: oprofile: Refactor common setup code for multiple driver support.Paul Mundt
This re-implements the old op_model_null code in to something more generic, where multiple drivers, backtrace, etc. can all be interfaced. Based largely on arch/mips/oprofile/common.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Enable GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH machinesMatt Fleming
After the recent changes to switch SuperH board support over to irq_chip it is now possible to set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Convert Cayman boards from hw_interrupt_type to irq_chipMatt Fleming
I've been unable to even compile-test this change because I don't have an sh5 toolchain. All uses of hw_interrupt_type for SuperH boards have now been converted to use irq_chip. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Convert Dreamcast support from hw_interrupt_type to irq_chipMatt Fleming
Switch the dreamcast IRQ code over to the irq_chip way of doing things, so that we can set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards. Also, whilst I'm here change some things to make checkpatch.pl happy: - Indent with tabs, not with spaces - Include <linux/io.h>, not <asm/io.h> - Fix the multi-line comment style - Fix some typos in the comments Tested-by: Adrian McMenamin <adrian@newgolddream.dyndns.info> Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: Convert Microdev boards from hw_interrupt_type to irq_chipMatt Fleming
This is part of the SH move to irq_chip. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Provide sdivsi3/udivsi3/udivdi3 for sh64, kill off libgcc linking.Paul Mundt
This moves in the necessary libgcc bits and kills off the libgcc linking for sh64 kernels as well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22fb: SH-5 uses __raw I/O accessors now also, drop the special casing.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Add SH-5 optimized memcpy()/memset()/strcpy()/strlen().Paul Mundt
Adopted from the uClibc optimized string versions. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off remaining CONFIG_SH_KGDB bits.Paul Mundt
Now that we use the generic stub, kill off all of the left over references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22serial: sh-sci: Implement CONSOLE_POLL support and kill off old kgdb console.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
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>
