2009-08-24sh: Allow for kernel command line concatenation.Pawel Moll
So far kernel command line arguments could be passed in by a bootloader or defined as CONFIG_CMDLINE, which completely overwriting the first one. This change allows a developer to declare selected kernel parameters in a kernel configuration (eg. project-specific defconfig), retaining possibility of passing others by a bootloader. The obvious examples of the first type are MTD partition or bigphysarea-like region definitions, while "debug" option or network configuration should be given by a bootloader or a JTAG boot script.

2009-08-23sh: let ARCH_SHMOBILE select PM and PM_RUNTIMEMagnus Damm
With the Runtime PM driver changes in place, we must have Runtime PM support in place. Otherwise there is no way to enable clocks to the Runtime PM enabled hardware blocks. This patch makes Runtime PM mandatory on SuperH Mobile. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-07-06sh: Add ftrace syscall tracing supportMatt Fleming
Now that I've added TIF_SYSCALL_FTRACE the thread flags do not fit into a single byte any more. Code testing them now needs to be aware of the upper and lower bytes. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-06sh: Define HAVE_FUNCTION_TRACE_MCOUNT_TESTMatt Fleming
Enable HAVE_FUNCTION_TRACE_MCOUNT_TEST and test the value of function_trace_stop from our assembly code as opposed to using the generic C function. This should optimise our mcount/ftrace code path. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-24sh: Fix up HAVE_PERF_COUNTERS typo.Paul Mundt
That's HAVE_PERF_COUNTERS not HAVE_PERF_COUNTER. This was right initially but I seem to have screwed it up while re-typing it out by hand on another machine when I checked it in. Hmph. Reported-by: Robert P. J. Day <rpjday@crashcourse.ca> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-23sh: SH7786 SMP support.Paul Mundt
SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2 CPUs. This just wraps in to the existing SH-X3 SMP code with some minor changes for SH7786, including wiring up the IPIs properly, enabling IRQ_PER_CPU, and so forth. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-23sh: Provide cpu_idle_wait() to fix up cpuidle/SMP build.Paul Mundt
Crib the x86 cpu_idle_wait() implementation and shove it in with the idle code, subsequently enabling ARCH_HAS_CPU_IDLE_WAIT. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-17sh: Generic HAVE_PERF_COUNTER support.Paul Mundt
This enables support for the generic software-based perf counters. Hardware counter support could be added in the future, but the lack of a performance counter IRQ makes this rather dubious. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-11sh: Tie sparseirq in to Kconfig.Paul Mundt
Now that the dependent patches are merged, we are ready to enable sparseirq support. This simply adds the Kconfig option, and then converts from the _cpu to the _node allocation routines to follow the upstream sparseirq API changes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-11sh: sh7722 clock framework rewriteMagnus Damm
This patch rewrites the sh7722 clock framework code. The new code makes use of the recently merged div4, div6 and mstp32 helper code. Both extal and dll are supported as input clocks to the pll. While at it, now when all SuperH Mobile processors are converted, fix CONFIG_SH_CLK_CPG_LEGACY to depend on CONFIG_ARCH_SHMOBILE.

2009-06-11sh: sh7724 clock framework rewrite V3Magnus Damm
This patch contains V3 of the sh7724 clock framework rewrite. The new code makes use of the recently merged div4, div6 and mstp32 helper code. Both extal and fll are supported as input clocks to the pll. The div6 clocks are fed through a divide-by-3 block.

2009-06-02sh: fix CONFIG_SH_PCLK_FREQ bug for sh7724Kuninori Morimoto
CONFIG_SH_PCLK_FREQ=33333333 is correct for sh7724. sh7724 master clock is 33333333, but peripheral is 41666666. This bug came to light because sh-sci driver had changed clk from "module_clk" to "peripheral_clk" Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-01sh: Tidy up SH-4A boot_cpu_data.flags probing.Paul Mundt
This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have a few things in common, which we can blindly set, rather than having each subtype have to set the same flags. We can also make assumptions about cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA as a config option. There was also a bug in the FPU probing, which is now tidied up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-22sh: clkfwk: Make clock-cpg usable for non-legacy platforms.Paul Mundt
This adds a new SH_CLK_CPG for parts that have CPG support. SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set for platforms that want clock-cpg to register the legacy clocks. With this new config item in place, it is now possible to start layering more generic CPG code in place while other platforms transition off of the legacy clocks. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-13sh: clkfwk: Update SH7785 for refactored clock framework.Paul Mundt
This updates the SH7785 CPU code as well as the SH7785LCR board support code for making use of the newly refactored clock framework. Support for the legacy CPG clocks is dropped at this point, with the extal frequency fed in from the board code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-13sh: clkfwk: Rework legacy CPG clock handling.Paul Mundt
This moves out the old legacy CPG clocks to their own file, and converts over the existing users. With these clocks going away and each CPU dealing with them on their own, CPUs can gradually move over to the new interface. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-12sh: Kill off the remnants of the old timer code.Paul Mundt
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>
2009-05-12sh: remove old TMU driverMagnus Damm
This patch removes the old TMU driver (CONFIG_SH_TMU/timer-tmu.c) As replacement, select the sh_tmu driver with CONFIG_SH_TIMER_TMU and configure timer channel using platform data. If multiple TMU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_tmu.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

2009-05-12sh: CMT platform data for sh7720/sh7721Magnus Damm
This patch adds CMT platform data for sh7720 and sh7721. All 5 32-bit CMT channels unfortunately share a single IRQ. 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: 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: 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: 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: 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>

2009-05-03clocksource: SuperH TMU Timer driverMagnus Damm
This patch adds a TMU driver for the SuperH architecture. The TMU driver is a platform driver with early platform support to allow using a TMU channel as clockevent or clocksource during system bootup or later. Clocksource or clockevent can be selected. Both periodic and oneshot clockevents are supported. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-05-03clocksource: SuperH MTU2 Timer driverMagnus Damm
This patch adds a MTU2 driver for the SuperH architecture. The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.
