| * | sh: dma: Kill off bogus dma_sysclass symbol export.Paul Mundt2009-11-12
| | | | | | | | | | | | | | | | | | | | | | | | This is a static symbol, so the export is wholly superfluous. Recent kbuild updates flagged this as an error, resulting in build failure, so this tidies that up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh64: Fix up reworked cache op build.Paul Mundt2009-11-12
| | | | | | | | | | | | | | | | | | | | | | | | This gets the build fixed up for the sh64 cache enabled case. Disabling still needs further abstraction for independent I/D-cache disabling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh64: Fix up the CONFIG_GENERIC_BUG=n build.Paul Mundt2009-11-12
| | | | | | | | | | | | | | | | | | | | | sh64 doesn't use GENERIC_BUG, which presently causes the handle_BUG() code to blow up. Fix up the dependencies and get it all building again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: Use the generic I/O port base for slowdown.Paul Mundt2009-11-12
| | | | | | | | | | | | | | | | | | | | | | | | This fixes up the build and behaviour for various configurations. Namely the CONFIG_32BIT cases where legacy mappings do not exist, as well as the sh64 build. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * | sh: Enable PMB support for all SH-4A CPUs.Paul Mundt2009-11-10
| | | | | | | | | | | | | | | | | | | | | | | | Presently the PMB options were limited to a number of CPUs they were tested with, but it is generally available on all SH-4A CPUs, so just drop the subtype conditionals. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * | | sh: oprofile: Fix up count size mismatch for common impl.Paul Mundt2009-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reduces the 'count' size in the common support structure to 32-bits so that it matches up with what oprofile is expecting. The SH7750 code was using a nasty oprofilefs hack to expose the 48-bit counter, although no other implementations were. Now that the offending driver has been killed off, it's possible to restore some semblance of sanity. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: oprofile: Kill off bitrotted SH7750 driver.Paul Mundt2009-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This kills off the old SH7750 oprofile driver, preferring perf instead. As this driver has a number of bugs that no one seems to have noticed, it's safe to kill this off now rather than providing an extended transition period. The old oprofile framework is still kept in place for now, primarily to give out-of-tree drivers a chance to transition off. But this too will be killed off in short order.

| * | | sh: perf events: Add support for SH7750-style counters.Paul Mundt2009-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds perf events support for the SH7750/SH7750S/SH7091 performance counters. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: perf events: Preliminary callchain support.Paul Mundt2009-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements preliminary support for perf callchains (at the moment only the kernel side is implemented). The actual implementation itself is just a simple wrapper around the unwinder API, which allows for callchain generation with or without the dwarf unwinder.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wanted by the SPU2 UIO driver, which really ought to be handling this itself. Default enable it for now, until the driver gets a bit more intelligent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'config' can be unintialized, and although it's not really an error, it still manages to trigger the -Werror with certain toolchains. Initialize it early to shut up gcc. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add sh7724 code to save and restore RWDT state during R-standby.

| * | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: perf events: Add preliminary support for SH-4A counters.Paul Mundt2009-10-28

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.
