| * | sh: Fix up read-only variable assignment in pcibios_align_resource().Paul Mundt2010-01-281-3/+1
| | | | | | | | | | | | | | | | | | arch/sh/drivers/pci/pci.c:167: error: assignment of read-only location '*res' Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: Mass ctrl_in/outX to __raw_read/writeX conversion.Paul Mundt2010-01-268-49/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old ctrl in/out routines are non-portable and unsuitable for cross-platform use. While drivers/sh has already been sanitized, there is still quite a lot of code that is not. This converts the arch/sh/ bits over, which permits us to flag the routines as deprecated whilst still building with -Werror for the architecture code, and to ensure that future users are not added.

| * | sh: Generalize SH7786 PCIe support.Paul Mundt2010-01-151-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | Previously this was only built in for Urquell boards, but the same approach can be used on SDK7786 now that the mode pin reading is supported, so make it generic to SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: heartbeat: Support access size specification via resource flags.Paul Mundt2010-01-151-5/+17
| |/ | | | | | | | | | | | | | | This permits the resource access size to be handed off through the resource flags, which saves platforms from having to establish platform data only to specify the register width. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | resource/PCI: mark struct resource as constDominik Brodowski2010-02-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | Now that we return the new resource start position, there is no need to update "struct resource" inside the align function. Therefore, mark the struct resource as const.

* | resource/PCI: align functions now return start of resourceDominik Brodowski2010-02-221-3/+3
|/ | | | | | | | | | | As suggested by Linus, align functions should return the start of a resource, not void. An update of "res->start" is no longer necessary.

* sh: dma: Kill off bogus dma_sysclass symbol export.Paul Mundt2009-11-131-2/+0
| | | | | | | | 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>
* sh: Kill off superfluous arch/sh/drivers/pci/Kconfig.Paul Mundt2009-10-271-7/+0
| | | | | | | | 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 Mundt2009-10-271-12/+0
| | | | | | | | | 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>

* | sh: Allow use of GENERIC_IOMAPDavid McKay2009-08-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The synopsys PCI cell used in the later STMicro chips requires code to be run in order to do IO cycles, rather than just memory mapping the IO space. Rather than extending the existing SH infrastructure to allow this, use the GENERIC_IOMAP implmentation to save re-inventing the wheel. This set of changes allows the SH to be built with GENERIC_IOMAP enabled, it just ifdef's out the functions provided by the GENERIC_IOMAP implementation, and provides a few required missing functions.

* | sh: Prevent heartbeat from scribbling over non-LED bits.Kuninori Morimoto2009-08-181-0/+10
|/ | | | | | | | | | While most platforms implement LED banks in sets of 8/16/32, some use different configurations. This adds a LED mask to the heartbeat platform data to allow platforms to constrain the bitmap, which is otherwise derived from the register size.

* sh: pci: Initial PCI-Express support for SH7786 Urquell board.Paul Mundt2009-06-172-0/+356
| | | | | | | | | | | | | This adds initial support for the PCI-Express module in the SH7786, particularly as it relates to the urquell platform. Presently it is only supported in root complex mode, with endpoint mode still requiring more debugging. 29/32-bit mode and lane configurations are selectable via board mode pins, and are otherwise fixed. Only 4x and 1x PCI channels are presently handled, the PCI bridge still requires additional debugging and stabilization in hardware. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: SH7786 PCI ops.Paul Mundt2009-06-163-0/+724

* sh: pci: Allow register_pci_controller() to handle overlapping regions.Paul Mundt2009-06-161-12/+2
| | | | | | | | Some host controllers (such as SH7786) have overlapping regions that are fixed in hardware. The resource allocator does the right thing in managing this space already, so the conflict case is non-fatal. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: pci-sh7780: Fix up for PCI_DISABLE_MWI changes.Paul Mundt2009-05-271-6/+1
| | | | | | | | This fixes a build error where references to pci_cache_line_size are undefined, as this ceases to be exported when PCI_DISABLE_MWI is enabled, as is now the default. 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: multiple vectors per irq - sh7760Magnus Damm2009-05-111-1/+2
| | | | | | | | | | | | Update intc tables and platform data to use one linux irq per maskable interrupt source instead of keeping the one-to-one mapping between vectors and linux irqs. This fixes potential irq masking issues for sh7760 hardware blocks such as DMAC/TMU2/REF. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt2009-05-071-2/+2
| | | | | | | | | | | Presently this is special-cased for early initialization. While there are situations where these static early initializations are still necessary, with minor changes it is possible to use this for the regular ioremap implementation as well. This allows us to kill off the special-casing for the remap completely and to start tidying up all of the SH-5 special-casing in drivers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | The se7751 was still doing the PCI fixups in its own board directory, so we move it over to arch/sh/drivers/pci/ with the rest of the board fixups.

* sh: pci: Rewrite SH7751 PCI support to follow SH7780.Paul Mundt2009-04-2010-305/+76
| | | | | | | | | This follows the similar sort of scheme that the refactored SH7780 code uses, using a 64MB CS3 mapping to handle the window0 case, and simply discarding window1. This vastly simplifies the code, and allows most of the board-specific setup to go die. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: pci: Consolidate the remaining common bits.Paul Mundt2009-04-203-116/+64
| | | | | | | | | | | This moves the remaining common bits in to pci-lib. Thereby reducing pci.c/pci-new.c to simple bus fixups and controller registration. As more platforms are moved over, the old code will disappear completely and the pci-new bits will be rolled in to pci-lib, eventually replacing pci.c completely.

* sh: pci: New-style controller registration.Paul Mundt2009-04-202-72/+112
| | | | | | | | This moves off of the board_pci_channels[] approach for bus registration and over to a cleaner register_pci_controller(), all derived from the MIPS code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate pci_iomap() and use the generic I/O base.Paul Mundt2009-04-203-70/+51
| | | | | | | | | | | This consolidates the pci_iomap() definitions and reworks how the I/O port base is handled. PCI channels can register their own I/O map base, or if none is provided, the system-wide generic I/O base is used instead. Functionally nothing changes, while this allows us to kill off lots of I/O address special casing and lookups. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off unused pcibios_fixup().Paul Mundt2009-04-201-5/+0
