2007-07-26sh: remove support for sh7300 and solution engine 7300Magnus Damm
This patch removes old dead code: - kill off sh7300 cpu support - get rid of broken solution engine 7300 board support Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-26sh: Kill off virt_to_bus()/bus_to_virt().Paul Mundt
Wire up ARCH_NO_VIRT_TO_BUS, and kill off the remaining users. The dma-mapping code really wanted virt_to_phys()/phys_to_virt() anyways, there are no inherently special bus addresses. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-26sh: Kill the rest of the SE73180 cruft.Paul Mundt
There was a stray header, and the mach-type removal was also missed. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-07-25sh: Reclaim beginning of P3 space for vmalloc area.Paul Mundt
The first 1MB of P3 space was reserved and used for page colouring, as we've reworked that to use fixmaps, we can reclaim the space and hand it back to VMALLOC_START. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-24sh: Fix Dreamcast DMA issues.Adrian McMenamin
The current SH DMA API is somewhat broken, not correctly matching virtual channel to the correct SH DMAC. This wasn't noticeable when using g2 DMA for the sound driver - one channel 0 is as good as any other! - but caused the pvr2 driver to fail. This patch fixes the pvr2 problem and consequently fixes the sound driver to ensure it continues to function.

2007-07-24sh: Add kmap_coherent()/kunmap_coherent() interface for SH-4.Paul Mundt
This wires up kmap_coherent() and kunmap_coherent() on SH-4, and moves away from the p3map_mutex and reserved P3 space, opting to use fixmaps for colouring instead. The copy_user_page()/clear_user_page() implementations are moved to this, which fixes the nasty blowups with spinlock debugging as a result of having some of these calls nested under the page table lock. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-20sh: intc - add support for SH7750 and its variantsMagnus Damm
This patch converts the cpu specific 7750 setup code to use the new intc controller. Many new vectors are added and multiple processor variants including 7091, 7750, 7750s, 7750r, 7751 and 7751r should all have the correct vectors hooked up. IRLM interrupts can be enabled using ipr_irq_enable_irlm() which now is marked as __init. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-07-20sh: Implement clk_round_rate() in the clock framework.Paul Mundt
This is an optional component of the clock framework. However, as we're going to be using this in the cpufreq drivers, add support for it to the framework. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-07-20sh: intc - add support for 7780Magnus Damm
This patch converts the cpu specific 7780 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type(). No external interrupts are registered by default. Use plat_irq_setup_pins() to select between IRQ or IRL mode. This patch also fixes the Alarm IRQ for the RTC.

2007-07-20sh: IPR/INTC2 IRQ setup consolidation.Magnus Damm
This patch unifies the cpu specific interrupt setup functions for interrupt controller blocks such as ipr, intc2 and intc. There is no point in having separate functions for each interrupt controller, so let's clean this up. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-20sh: clean up interrupt code for solution engine 7722 boardMagnus Damm
This patch cleans up solution engine 7722 specific interrupt code. The main purpose is to replace the mux function with use of set_irq_chained_handler() and replace hard coded register poking code with set_irq_type(). The board specific interrupts are also moved to start from SE7722_FPGA_IRQ_BASE. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-20sh: intc - add support for 7722 processorMagnus Damm
This patch converts the cpu specific 7722 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type().

2007-07-20sh: intc - shared IPR and INTC2 controllerMagnus Damm
This is the second version of the shared interrupt controller patch for the sh architecture, fixing up handling of intc_reg_fns[]. The three main advantages with this controller over the existing ones are: - Both priority (ipr) and bitmap (intc2) registers are supported - External pin sense configuration is supported, ie edge vs level triggered - CPU/Board specific code maps 1:1 with datasheet for easy verification This controller can easily coexist with the current IPR and INTC2 controllers, but the idea is that CPUs/Boards should be moved over to this controller over time so we have a single code base to maintain.

New arch macro STACK_TOP_MAX it gives the larges valid stack address for the architecture in question. It differs from STACK_TOP in that it will not distinguish between personalities but will always return the largest possible address. This is used to create the initial stack on execve, which we will move down to the proper location once the binfmt code has figured out where that is.

2007-07-11PCI: Use a weak symbol for the empty version of pcibios_add_platform_entries()Michael Ellerman
I'm not sure if this is going to fly, weak symbols work on the compilers I'm using, but whether they work for all of the affected architectures I can't say. I've cc'ed as many arch maintainers/lists as I could find. But assuming they do, we can use a weak empty definition of pcibios_add_platform_entries() to avoid having an empty definition on every arch.

2007-06-18sh: Fix up futex implementation.Kaz Kojima
SH is able to support a complete futex implementation on UP by way of gUSA. However, IRQ toggling must be done for the old CPUs that don't have movli.l/movco.l (LL/SC) instructions. Provide a default implementation that does this, so it's possible to optimize for newer CPUs. Follows the same scheme as the current asm-sh/atomic-*.h headers.

2007-06-15sh: rework ipr codeMagnus Damm
This patch reworks the ipr code by grouping the offset array together with the ipr_data structure in a new data structure called ipr_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks. This strategy has much in common with the recently merged intc2 code. One logic change has been made - the original ipr code enabled the interrupts by default but with this patch they are all disabled by default.

2007-06-15sh: rework intc2 codeMagnus Damm
The shared intc2 code currently contains cpu-specific #ifdefs. This is a tad unclean and it prevents us from using the shared code to drive board-specific irqs on the se7780 board. This patch reworks the intc2 code by moving the base addresses of the intc2 registers into struct intc2_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks.

2007-06-11sh: Tidy up dependencies for SH-2 build.Paul Mundt
SH-2 can presently get in to some pretty bogus states, so we tidy up the dependencies a bit and get it all building again. This gets us a bit closer to a functional allyesconfig and allmodconfig, though there are still a few things to fix up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-11sh: Compile fix for SH7604 removal.Paul Mundt

2007-06-08sh: Kill off dead SH7604 support.Paul Mundt
This was added during 2.5.x, but was never moved along. This can easily be resurrected if someone has one they wish to work with, but it's not worth keeping around in its current form. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Support for multiple nodes.Paul Mundt
This adds basic support for multiple nodes on SH machines. This is primarily useful for boards with many different memory blocks that are otherwise unused (SH7722/SH7785 URAM and so forth). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Default to 4-byte alignment for SLUB objects.Paul Mundt
Slub currently defaults to 8-byte alignment for the kmalloc and slab minalign values, where 4 will suffice. In the slab case BYTES_PER_WORD == 4 already, so defining the minalign values outright doesn't cause any regressions there either. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: sparsemem support.Paul Mundt
This implements basic sparsemem support for SH. Presently this only uses static sparsemem, and we still permit explicit selection of flatmem. Those boards that want sparsemem can select it as usual. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: pfn_valid() depends on flatmem.Paul Mundt
pfn_valid() is already defined in the sparsemem case, so we only need to define this for CONFIG_FLATMEM. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Kill off machvec aliases.Paul Mundt
We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Get multiple boards in one image working again.Paul Mundt
This tidies up the build rules and permits multiple boards to be linked in to the same kernel. The earlier Kconfig work ensures that the CPU configuration is consistent across the boards, as this is the only thing that we can't do dynamically. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fixup machvec support.Paul Mundt
This fixes up much of the machvec handling, allowing for it to be overloaded on boot. Making practical use of this still requires some Kconfig munging, however. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: __user annotations for __get/__put_user().Paul Mundt
This adds in some more __user annotations. These weren't being handled properly in some of the __get_user and __put_user paths, so tidy those up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Just at the time you added them on sh we're removing them from other architectures. As there's no user yet this patch just removes them completely.
