2009-05-10sh: Merge the split arch/sh/boot/compressed/ Makefiles.Paul Mundt
This kills off the _64 variant and moves the _32 one over as the generic one to use. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-10sh: Provide a BITS definition, use it in the arch/sh/boot/ Makefiles.Paul Mundt
This introduces a BITS export that can handily be picked up by Makefiles for cleaner sharing. Reflect its use in arch/sh/boot/compressed/ in preparation for unifying the Makefiles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-10sh: Provide a tighter BOOT_LINK_OFFSET definition for the Cayman board.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-10sh: Fix up the sh64 zImage build.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-10sh: Tidy up the ldscript output format specifier.Paul Mundt
Tie this in to the Makefile directly, where we already know what we are running on. This tidies up the linker script a bit, and is prep work for unifying the arch/sh/boot/compressed linker scripts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Move the unified linker script in place, kill off old _64 one.Paul Mundt
Just forcefully rename the _32 variant overtop, and kill off the now unused _64 version. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Integrate sh64 bits in vmlinux_32.lds.S.Paul Mundt
This adds all of the requisite bits from vmlinux_64.lds.S in to the _32 variant, resulting in a unified and generic linker script that can be shared across both. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Fix up SHmedia module ELF relocations.Paul Mundt
This fixes up the LSB setting for SHmedia branching in updated symbols when processing module relocations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Provide an __sdivsi3_2 export for sh64.Paul Mundt
Newer code paths that are heavier in 64-bit math manage to get this generated by newer compilers, provide a definition and export accordingly. This is trivially wrapped around the existing __sdivsi3 code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Rename opcode_t to insn_size_t.Paul Mundt
This is now clashing with a driver, so just rename it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Provide __read_{read,write}sl() definitions for sh64.Paul Mundt
These are presently only defined for sh32, use the plain unoptimized versions for sh64. Fixes up smsc911x build. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Cleanup irqflags size mismatch on SH-5 build.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Add UBC trap vector for SH2APeter Griffin
Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Add ptrace support for NOMMU debuggingPeter Griffin
Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Fix UBC setup and registers for SH2AKieran Bingham
Signed-off-by: Kieran Bingham <kieranbingham@gmail.com> Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-09sh: Add in some ptrace definitions from GDB.Kieran Bingham
Plugs in PT_TEXT_END_ADDR/PT_TEXT_ADDR/PT_DATA_ADDR/PT_TEXT_LEN definitions. Signed-off-by: Kieran Bingham <kieranbingham@gmail.com> Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Add clock id to sh-sci platform data on SH-Mobile CPUs.Paul Mundt
This adds the clock specifier to all of the SH-Mobile sh-sci ports. Impacted CPUs are SH7343/SH7366/SH7722/SH7723/SH7724. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off the GENERIC_CALIBRATE_DELAY ifndef.Paul Mundt
Now that everyone is using the clock framework directly and we unconditionally provide our own calibrate_delay() function, having it wrapped in an ifndef is no longer useful. So, kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: TMU platform data for SH-X3 proto CPU.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: TMU platform data for SH7786.Paul Mundt
Wires up all 12 TMU channels, with TMU0 and 1 used as clockevent and clocksource respectively. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Always fixup unaligned userspace accesses on sh64.Paul Mundt
sh64 has traditionally had this configurable via a Kconfig option (CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been terribly useful to turn this off, so just get rid of the option entirely. We leave the sysctl around so we don't end up breaking existing root file systems, and to allow folks that really want this off to do so at their own risk. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off extra cflags Kconfig entry.Paul Mundt
There is no real reason to use this anymore, as the build system generally knows what it is doing with regards to cflags mangling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Always select RTC_LIB, not just for SUPERH32.Paul Mundt
The RTC_LIB helpers are used in arch/sh/kernel/time.c, which was previously only the case for the 32-bit variant. Now that this has become the common implementation, move the RTC_LIB select to reflect that. Fixes up the sh64 build. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Drop dead rules from arch/sh/kernel/Makefile_64.Paul Mundt
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>
2009-05-08sh: TMU platform data for sh7723Magnus Damm
This patch adds TMU platform data for sh7723. Both clockevent and clocksource support is enabled. While at it, adjust the CMT clocksource rating to prioritize the TMU. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: enable TMU clocksource on sh7722Magnus Damm
This patch enables the TMU clocksource on sh7722. To prioritize TMU over CMT we also adjust the CMT clock source rating. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: clock framework update, fix count and kill off krefMagnus Damm
This patch updates the clock framework use count code. With this patch the enable() and disable() callbacks only get called when counting from and to zero. While at it the kref stuff gets replaced with an int. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Move out cayman-specific panic handler code to its own file.Paul Mundt
This moves out the cayman-specific panic handler code to a better location, and leaves the generic implementation a simple stub that is still used under emulation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off unused sh64 debug code.Paul Mundt
None of the print_page() code and associated helpers are presently used by anything in-tree, so just kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off sh64's hand-rolled syscall tracer.Paul Mundt
This is no longer necessary, as there are now sufficient generic alternatives available. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off the global rtc_lock with extreme prejudice.Paul Mundt
Now that all of the possible users for rtc_lock have gone away, it is no longer necessary to keep this lock definition around. This follows several other architectures that have either recently dropped it or never supported it in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: mach-sh03: Give the sh03 rtc its own spinlock.Paul Mundt
This converts the sh03 rtc code off of using the global rtc_lock and on to its own spinlock. There are no other possible users of the rtc_lock, so serializing with it is not necessary. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off dead timer sysclass pm hooks.Paul Mundt
With the conversion to generic clockevents these are completely unused, so just kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off dead handle_timer_tick() code.Paul Mundt
Nothing is using this anymore now that we have fully converted to generic time, so kill it off completely. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Wire up GENERIC_CMOS_UPDATE for the platforms that need it.Paul Mundt
Now that everything has converted over to generic timekeeping, we need an alternate method for keeping the RTC updated for those platforms that are still using the rtc_sh_get/set_time pairs, presently limited to SH-03 and the Dreamcast. This wires up the GENERIC_CMOS_UPDATE hooks for those to maintain the same behaviour. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Rename arch/sh/kernel/time_32.c to arch/sh/kernel/time.c.Paul Mundt
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>
2009-05-08sh: Finish the sh64 migration off of ARCH_USES_GETTIMEOFFSET.Paul Mundt
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>
2009-05-08sh: Move out rtc-sh registration from time_64.c to setup-sh5.cPaul Mundt
Now that the onchip_remap() mess is sorted out, the rtc-sh support code for SH-5 can follow the same approach as the other CPUs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Enable new TMU driver support for all SH-3 and SH-4 CPUs.Paul Mundt
The TMU block is supported on all SH-3 and SH-4 subtypes, so just select it there, rather than conditionalizing it per subtype. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: TMU platform data for sh7785Magnus Damm
This patch adds TMU platform data for sh7785. Both clockevent and clocksource support is enabled. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: r7785 highlander clock fixesMagnus Damm
Update the r7785 highlander defconfig to fix PCLK value and that mode4 is set high. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: call clock framework init() callback onceMagnus Damm
Make sure that clk->ops->init() only gets called once in the case of CLK_ALWAYS_ENABLED. Without this patch the init() callback may be called multiple times. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: sh7785 early scif fixMagnus Damm
This patch moves the SH4 case of EARLY_SCIF_CONSOLE_PORT so the SH7785 default value gets used. Without this patch the value for SH7785 is set to 0xffe80000. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-07sh: Kill off unused SH-5 irq_describe cruft.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-07sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt
Presently this is special-cased for early initialization. While there are situations where these static early initializations are still necessary, with minor changes it is possible to use this for the regular ioremap implementation as well. This allows us to kill off the special-casing for the remap completely and to start tidying up all of the SH-5 special-casing in drivers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-07sh: sh64 still needs ARCH_USES_GETTIMEOFFSET temporarily.Paul Mundt
sh64 is still using this, so re-enable it temporarily while SH-5 gets converted to use the generic code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-07sh: Handle shm_align_mask also for HAVE_ARCH_UNMAPPED_AREA_TOPDOWN.Paul Mundt
Presently shm_align_mask is only looked at for the bottom up case, but we still want this for proper colouring constraints in the topdown case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-07sh: Flag IRQSTACKS as BROKEN for now.Paul Mundt
There still seems to be some stack corruption to sort out here, so flag this as BROKEN until this issue is sorted out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-03sh: Move dummy clockevents broadcast timer to its new home.Paul Mundt
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>
2009-05-03sh: Kill off the now unused ARCH_USES_GETTIMEOFFSET code.Paul Mundt
Now that the stragglers (MTU2/CMT/etc.) have been rewritten and we are selecting both GENERIC_TIME and GENERIC_CLOCKEVENTS, the get_offset() timer op is completely unused. As a result, we are now able to kill off the ARCH_USES_GETTIMEOFFSET references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
