* sh: pci: Disable MWI and make pci_dma_burst_advice() a bit more accurate.Paul Mundt2009-05-261-2/+18
| | | | | | | | | None of the SH PCI controllers support MWI, it is always treated as a direct memory write, so simply disable it outright. In the case of the PCI cache line size, consult that for the pci_dma_burst_advice() strategy, and switch over to PCI_DMA_BURST_MULTIPLE, as PPC64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci-sh7751: Initialize io_map_base in controller definition.Paul Mundt2009-05-261-3/+2
| | | | | | | | | As there is only a single controller and remapping has no impact for the address range in question, just initialize it directly in the controller definition. This fixes up boot time warnings about not having the field initialized. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Prefer slab_is_available() over after_bootmem.Paul Mundt2009-05-222-4/+2
| | | | | | | | This kills off after_bootmem and switches to using slab_is_available() instead. Presently the only place this is used is by the sh64 ioremap, and there's not much point in keeping the reference around otherwise. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add a NR_IRQS_LEGACY for external IRQ0-7.Paul Mundt2009-05-221-1/+2
| | | | | | This adds a NR_IRQS_LEGACY definition, which will be used by sparse irq. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Wrap irq_to_desc_alloc_cpu() around CONFIG_SPARSE_IRQ temporarily.Paul Mundt2009-05-222-1/+8
| | | | | | | | | irq_to_desc_alloc_cpu() has been renamed to irq_to_desc_alloc_node() in -next, but as we can not presently enable SPARSE_IRQ without the early irq_desc alloc patch, protect it with an ifdef until the interface has settled and we are ready to enable it system-wide.

| * sh: irq: Provide an arch_probe_nr_irqs() that wraps the machvec def.Paul Mundt2009-05-221-0/+8
| | | | | | | | | | | | | | | | This is just a simple arch_probe_nr_irqs() stub that wraps to the platform defined number of IRQs. This can be made gradually more intelligent based on what we can infer from the INTC tables and so on. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: irq: Teach ipr and intc about dynamically allocating irq_descs.Paul Mundt2009-05-222-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This hooks in irq_to_desc_alloc_cpu() to the necessary code paths in the intc and ipr controller registration paths. As these are the primary call paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready. There is the added benefit now that each CPU contains specific IPR and INTC tables, so only the vectors with interrupt sources backing them will ever see an irq_desc instantiation. This effectively packs irq_desc down to match the CPU, rather than padding NR_IRQS out to cover the valid vector range. Boards with extra sources will still have to fiddle with the nr_irqs setting, but they can continue doing so through the machvec as before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: irq: Convert from irq_desc[] to irq_to_desc().Paul Mundt2009-05-223-39/+48
| | | | | | | | | | | | | | | | This converts a few places that were using the old irq_desc[] array over to the shiny new irq_to_desc() helper. Preperatory work for sparse irq support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: irq: Rework the SR.IMASK bitmap handling.Paul Mundt2009-05-221-48/+16
| | | | | | | | | | | | | | | | This tidies up how the SR.IMASK bitmap is managed, using the bitmap API directly instead. At the same time, tidy up the irq_chip conversion a bit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: mach-hp6xx: Fix up the hp6xx build for hd64461 changes.Paul Mundt2009-05-203-4/+4

| * sound: oss: sh_dac_audio timer fixes.Magnus Damm2009-05-152-54/+33
| | | | | | | | | | | | | | | | | | | | | | This patch modifies sh_dac_audio in the following ways: - use high resolution timer instead of TMU1 - fix cpu/dac.h include - add future rewrite comment Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: hd64461: Fix up I/O base register offsets.Paul Mundt2009-05-152-77/+74
| | | | | | | | | | | | | | | | | | | | hd64461 is mapped in a fixed location, so the I/O base itself is fairly meaningless as a configuration item. Additionally, this makes it impossible to share hd64461 code alongside generic drivers (in the case of sh_dac_audio), so simply make it commonly defined and permit the mach_is_foo() logic to work out the proper semantics.

| * sh: Provide FORCE_MAX_ZONEORDER.Paul Mundt2009-05-141-0/+23
| | | | | | | | | | | | | | | | | | Several platforms want to be able to do large physically contiguous allocations (primarily nommu and video codecs on SH-Mobile), provide a MAX_ORDER override for those cases.

| | | | | | | | | | | | | | | | 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>
| * sh: remove old TMU driverMagnus Damm2009-05-127-438/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is nothing in these routines that inherently depends on R0 use. Given that these routines are inlined, it is rather easy to blow up the compiler by exhausting the spill class when performing a 64-bit swab. This presently manifests itself as the following: CC fs/ocfs2/suballoc.o fs/ocfs2/suballoc.c: In function 'ocfs2_reserve_suballoc_bits': fs/ocfs2/suballoc.c:638: error: unrecognizable insn: (insn 2793 1230 1231 103 arch/sh/include/asm/swab.h:33 (set (reg:HI 853) (subreg:HI (reg:SI 149 macl) 2)) -1 (expr_list:REG_DEAD (reg:SI 149 macl) (nil))) fs/ocfs2/suballoc.c:638: internal compiler error: in extract_insn, at recog.c:1991 This patch switches over to using an arbitrarily assigned register instead.
