* sh: Add RWDT save/restore code for sh7724 R-standbyMagnus Damm2009-11-03
| | | | | | | | | Add sh7724 code to save and restore RWDT state during R-standby. Without this patch the watchdog will generate a reset shortly after resuming from R-standby. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: mach-se: Convert SE7722 FPGA to dynamic IRQ allocation.Paul Mundt2009-11-03
| | | | | | | | | This gets rid of the arbitrary set of vectors used by the SE7722 FPGA interrupt controller and witches over to a completely dynamic set. No assumptions regarding a contiguous range are made, and the platform resources themselves need to be filled in lazily. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc: Handle legacy IRQ reservation in vector map.Paul Mundt2009-11-02
| | | | | | | | | | | | | Different CPUs will have different starting vectors, with varying amounts of reserved or unusable vector space prior to the first slot. This introduces a legacy vector reservation system that inserts itself in between the CPU vector map registration and the platform specific IRQ setup. This works fine in practice as the only new vectors that boards need to establish on their own should be dynamically allocated rather than arbitrarily assigned. As a plus, this also makes all of the converted platforms sparseirq ready. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Remove unused WP signal for SDHI0 and KFR2R09Magnus Damm2009-11-02
| | | | | | | | | Get rid of the unused WP signal for SDHI0 on KFR2R09. This because yc304 on KFR2R09 is a Micro SD slot which does not implement the WP signal. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add SDHI1 support to the AP325RXA boardMagnus Damm2009-11-02

* sh: Use RSMEM for sleep code on sh7724Magnus Damm2009-10-30
| | | | | | | | Use RSMEM instead of ILMEM for sleep mode code storage on SH7724. This allows us to use R-standby mode on SH7724. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add MMU and Cache handling sleep mode codeMagnus Damm2009-10-30
| | | | | | | | | | | | Add MMU and cache handling functionality to the SuperH Mobile sleep code. The MMU and cache registers are saved and restored. The MMU is disabled and the cache is flushed and disabled before entering sleep modes if the SUSP_SH_MMU flag is set. This flag should be set in the case of R-standby and most likely for future U-standby support as well. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Keep track of allowed sleep modesMagnus Damm2009-10-30
| | | | | | | | | | Add code to keep track of supported sleep modes. This to only export cpuidle modes that are backed by board support code. Also, do not allow suspend-to-ram if sdram board code is missing. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Rework SuperH Mobile sleep mode codeMagnus Damm2009-10-30
| | | | | | | | | | Rework the SuperH Mobile sleep code from including board specific code to allowing each board to provide pre/post code snippets. These snippets should contain sdram management code to enter and leave self-refresh. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | Move the AP325RXA board code from a single board file to a separate directory. This to make it easy to add support for sdram sleep mode code. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Allow boards to register memory pre/post sleep codeMagnus Damm2009-10-29
| | | | | | | | | | | Add code to allow boards registering self-contained functions for going to/from self-refresh. At this point the board code is unused. When all supported boards have been converted then the new sleep code will make use of these functions. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add sh7724 notifier for R-standby save/restoreMagnus Damm2009-10-29

* sh: Add notifiers chains for cpu/board codeMagnus Damm2009-10-29
| | | | | | | | | | This patch adds atomic notifier chains for pre/post sleep events. Useful for cpu code and boards that need to save and restore register state before and after entering a sleep mode. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Do not apply virt_to_phys() to a physical addressMatt Fleming2009-10-29
| | | | | | | | The variable 'phys' already contains the physical address to flush. It is not a virtual address and should not be passed to virt_to_phys(). Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: perf events: Kill off left over debugging cruft.Paul Mundt2009-10-28
| | | | | | | num_events should be compared > MAX_HWEVENTS and not >=. The latter was used as a debugging test which accidentally slipped in. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: perf events: Add preliminary support for SH-4A counters.Paul Mundt2009-10-28
| | | | | | | | | | | | | | This adds in preliminary support for the SH-4A performance counters. Presently only the first 2 counters are supported, as these are the ones of the most interest to the perf tool and end users. Counter chaining is not presently handled, so these are simply implemented as 32-bit counters. This also establishes a perf event support framework for other hardware counters, which the existing SH-4 oprofile code will migrate over to as the SH-4A support evolves.

| * sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.Paul Mundt2009-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

* | sh: Bump up dma_ops initialization far earlier in the boot process.Paul Mundt2009-10-27
| | | | | | | | | | | | | | | | | | | | | | Presently this was tacked on to the dma debug init bits from fs_initcall(), which is far too late for devices setting up their own per-device coherent areas. Throw this in the beginning of mem_init(), as per the x86 iommu allocation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh: Clean up more superfluous symbol exports.Paul Mundt2009-10-26

* | sh: Kill off superfluous arch/sh/drivers/pci/Kconfig.Paul Mundt2009-10-26
| | | | | | | | | | | | | | | | Now that this contains a grand total of 1 Kconfig option, it's hardly worth keeping split out. Roll CONFIG_PCI back in to the top-level architecture Kconfig, along with the other bus types. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh: Revamp PCI DMA coherence Kconfig bits.Paul Mundt2009-10-26
| | | | | | | | | | | | | | | | | | Leaving this configurable caused more trouble than it was ever worth, so just make it explicit. Boards that are verified one way or the other can fix up their selects accordingly. We presently default to non-coherent for most platforms. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | Now that SH's irqflags functions are out of line it becomes necessary to mark them as "notrace" so that we don't try to trace them.

| * sh: Check for return_to_handler when unwinding the stackMatt Fleming2009-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.
