* sh: Fix up the SH-3 build.Paul Mundt2010-10-061-0/+1
| | | | | | | | | | SH-3 lacks an MMUCR_TI definition for global TLB flushes. As SH-3 parts lack a split TLB, the same global flush behaviour is accomplished through the flush bit, which just happens to be the same as on SH-4. This fixes up the build for all SH-3 MMU parts.

* sh: fix uninitialized spinlockAkinobu Mita2010-10-061-1/+1
| | | | | | | | | | | The spinlock in traps_64.c is used without initialization. This fixes it by declaring DEFINE_SPINLOCK() and makes the spinlock static variable.

* sh: Wire up INTC subgroup splitting for SH7786 SCIF1.Paul Mundt2010-10-051-38/+72
| | | | | | | | SH7786 is the big user for subgroup splitting, mostly for the PCIe block, but those will follow later. For now we simply split up SCIF1, as used by the serial console on SDK7786 and others. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc: Support virtual mappings for IRQ subgroups.Paul Mundt2010-10-041-0/+2
| | | | | | | | | | | | | | | | | | | | Many interrupts that share a single mask source but are on different hardware vectors will have an associated register tied to an INTEVT that denotes the precise cause for the interrupt exception being triggered. This introduces the concept of IRQ subgroups in the intc core, where a virtual IRQ map is constructed for each of the pre-defined cause bits, and a higher level chained handler takes control of the parent INTEVT. This enables CPUs with heavily muxed IRQ vectors (especially across disjoint blocks) to break things out in to a series of managed chained handlers while being able to dynamically lookup and adopt the IRQs created for them. This is largely an opt-in interface, requiring CPUs to manually submit IRQs for subgroup splitting, in addition to providing identifiers in their enum maps that can be used for lazy lookup via the radix tree.

* sh: Drop __initdata for SH-X3 pinmux tables.Paul Mundt2010-10-031-5/+5
| | | | | | | The gpio sysfs support needs to get at these later, so drop the __initdata annotations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: mach-x3proto: Improve ILSEL debugging.Paul Mundt2010-10-031-4/+12
| | | | | | | | | At the moment ILSEL blows up with a BUG when aliased sets are handed in, but as the enable call is able to hand back errors we opt for that path instead. None of the ILSEL peripherals are vital to the board's operation, so trapping a BUG is a bit excessive. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: mach-x3proto: gpio-keys support.Paul Mundt2010-10-031-2/+105
| | | | | | | This adds gpio-keys mappings for the button matrix on the baseboard, now that we have support for the pin controller. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: mach-x3proto: Support for baseboard GPIOs.Paul Mundt2010-10-033-0/+149
| | | | | | | This adds trivial support for the GPIOs implemented through the baseboard CPLD, used for driving the button matrix. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: mach-x3proto: Move the ilsel header to a better place.Paul Mundt2010-10-033-2/+2
| | | | | | | We'll be adding more headers for this board, so move this over to its own directory. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Allow GPIO chips to register IRQ mappings.Paul Mundt2010-10-021-4/+2
| | | | | | | As non-PFC chips are added that may support IRQs, pass through to the generic helper instead of triggering the WARN_ON(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Support early IRQ vector map reservation for delayed controllers.Paul Mundt2010-10-022-9/+17
| | | | | | | | | | Some controllers will need to be initialized lazily due to pinmux constraints, while others may simply have no need to be brought online if there are no backing devices for them attached. In this case it's still necessary to be able to reserve their hardware vector map before dynamic IRQs get a hold of them. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Handle pinmux for SH-X3 proto IRQ/IRL modes.Paul Mundt2010-10-022-0/+25
| | | | | | | | The SH-X3 proto CPU has all of the external IRQ and IRL pins muxed, make sure that we're able to grab them before attempting to register their respective IRQ controllers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pinmux support for SH-X3 proto CPUs.Paul Mundt2010-10-023-0/+652
| | | | | | | This adds in support for GPIO/pinmux on the SH-X3 proto CPUs. This will subsequently be used by the x3proto board. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Support IRQ balancing for SH-X3 proto cores, too.Paul Mundt2010-10-011-4/+11
| | | | | | | This adds in hardware IRQ auto-distribution support for SH-X3 proto CPUs, following the SH7786 support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Support userimask for all SH-X3 interrupt controllers.Paul Mundt2010-10-013-18/+36
| | | | | | | | This shuffles some of the shared bits out of the 7786 code and in to a shared SH-X3 support file. Presently just for userimask, but also a good place for the IRQ balancing wrappers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: boot kernel with SR.BL setMagnus Damm2010-09-303-2/+7
| | | | | | | | | | | | | | | | | | | | | | Update the SH kernel to keep SR.BL set until the VBR register has been initialized. Useful to allow boot of the kernel even though exceptions are pending. Without this patch there is a window of time when exceptions such as NMI are enabled but no exception handlers are installed. This patch modifies both the zImage loader and the actual kernel to boot with BL=1, but the zImage loader is modfied in such a way that the init_sr value is unchanged to not break the zImage loader provided by kexec. Tested on sh7724 Ecovec and on the SH4AL-DSP core included in sh7372. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: fix a kfree address in clkdev codeGuennadi Liakhovetski2010-09-301-1/+3
| | | | | | | | | | kfree() in clkdev_drop() function should actually be called with an address of a struct clk_lookup_alloc object, and not struct clk_lookup, as presently done. This just happens to work, because "struct clk_lookup cl" is the first member in struct clk_lookup_alloc.

* sh: provide generic arch_debugfs_dir.Paul Mundt2010-09-238-40/+24
| | | | | | | | | While sh previously had its own debugfs root, there now exists a common arch_debugfs_dir prototype, so we switch everything over to that. Presumably once more architectures start making use of this we'll be able to just kill off the stub kdebugfs wrapper. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: pci: Use a generic raw spinlock for PCI config access locking.Paul Mundt2010-09-204-12/+17
| | | | | | | | | | This copies the pci_config_lock idea from x86 over, allowing us to kill off a couple of existing private locks. At the same time, these need to be converted to raw spinlocks for -rt kernels, so we make that change at the same time. This should make it easier for future parts to get the locking right instead of inevitable ending up with lock type mismatches. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: clock framework support for SH7786 PCIe.Paul Mundt2010-09-201-21/+86
| | | | | | | This gets each port handling its MSTP bit, as well as moving the PHY clock management in to the clock framework. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Use I/O accessors consistently in SH7786 PCIe init code.Paul Mundt2010-09-202-17/+25
| | | | | | | | Some of the existing code is flipping between __raw_xxx() and pci_{read,write}_reg(). As the latter are just wrappers for the former, flip over to using them consistently. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Support ports with disabled links on SH7786 PCIe.Paul Mundt2010-09-201-5/+12
| | | | | | | | | Presently we error out if a link is disabled and simply drop the port registration outright. This follows the PPC changes and simply reports on the link state on boot, leaving the port registered, in order to more easily deal with hotplug on future parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Discard initial PCICONF4/5 settings for SH7786 PCIe.Paul Mundt2010-09-201-3/+0
| | | | | | | These settings are properly propagated by the hardware already, so there's no need to bother with them manually. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Support root complex config accesses on SH7786 PCIe.Paul Mundt2010-09-202-9/+55
| | | | | | | | | | | | | | | | | | | | The SH7786 PCIe is presently unable to enumerate itself in root complex mode, and has no visibility through either type 0 or type 1 accesses, despite having a mostly sensible extended config space for each port. Attempts to generate type 0 or type 1 config cycles result in completer aborts, so we're ultimately forced to use SuperHyway transactions instead. As each port has a single port <-> device mapping that resolves for any PCI_SLOT definition, we simply hijack devfn 0 for the SuperHyway transaction and bump up the devfn limit. With enumeration of the root complex now possible, we also need to insert an early fixup to hide the BARs from the kernel. With all of that done, it's now possible to use the pcieport services with all of the PCIe ports, which is the first step to power management support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Move Renesas PCI IDs to a better place.Paul Mundt2010-09-201-6/+0
| | | | | | | | Previously these IDs were only used by one driver, so there was not much need for having them generically defined. Now that this will no longer hold true, move them over. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Give SH7786 PHY some time to settle.Paul Mundt2010-09-191-0/+3
| | | | | | | | | | The spec suggests waiting up to 500ms for the PHY to settle before testing link state, but practice shows that 100ms is sufficient (this is the delay value we also use on the other SH-4A PCI controllers, too). This makes device detection much more reliable, although in the future it should be a bit faster to simply serialize with a TLP IRQ. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | Now that the rest of the socket calls are provided through their own paths, do the same for sys_recvmmsg. It's unlikely we'll ever be able to kill off the socketcall path, but this at least permits userspace to gradually begin migrating. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add syscall entries for non multiplexed socket callsCarmelo AMOROSO2010-09-142-1/+38
| | | | | | | | | | | | Linux kernel already has socket syscalls that can be invoked without the multiplexing sys_socketcall wrapper. C library wrappers are ready to use them directly. It needs just to define the missing syscall numbers and provide the related entries into the syscalls table, like sh64 aleady does.

| | | | | | | | | | | | | | | | | | Certain memory windows are only available for 32-bit space, so skip over these in 29-bit mode. This will severely restrict the amount of memory that can be mapped, but since a boot loader bug makes booting in 29-bit mode close to impossible anyways, everything is ok.
