* sh: pci-sh7780: Fix up for PCI_DISABLE_MWI changes.Paul Mundt2009-05-26
| | | | | | | | 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 Mundt2009-05-26
| | | | | | | | | 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 Damm2009-05-11
| | | | | | | | | | | | 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 Mundt2009-05-07
| | | | | | | | | | | 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>
* sh: pci: Rename pci-new.c to pci.c.Paul Mundt2009-04-20
| | | | | | | pci-new.c is now in a state to replace the old pci.c, rename it accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Roll pci-lib in to pci-new.Paul Mundt2009-04-20
| | | | | | | Now that the pci-auto cruft is gone, pci-lib can go away. Roll it back in to pci-new.c where it originally split off from. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off the last remnants of the now unused pci-auto code.Paul Mundt2009-04-20
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Move the se7751 fixups in to arch/sh/drivers/pci/.Paul Mundt2009-04-20
| | | | | | | | | 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. It has bitrotted significantly over the years, so will still likely need a bit of work to bring back up to date. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Convert dreamcast to new-style interface.Paul Mundt2009-04-20
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate lboxre2 and r2d IRQ fixups.Paul Mundt2009-04-20
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Rename SH7751 platform ops files to fixups.Paul Mundt2009-04-20
| | | | | | | None of these contain pci_ops, only IRQ routing bits, rename them accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Rewrite SH7751 PCI support to follow SH7780.Paul Mundt2009-04-20
| | | | | | | | | 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: Rename ops-cayman -> fixups-cayman.Paul Mundt2009-04-20
| | | | | | Now that ops-cayman.c only contains IRQ routing fixups, rename it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Convert the SH-5 code over to the new interface.Paul Mundt2009-04-20
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Tidy up the dreamcast PCI support.Paul Mundt2009-04-20
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off legacy ide quirks.Paul Mundt2009-04-20
| | | | | | | | These fixups seem to have bitrotted a bit since their introduction in the 2.4 days. As we never had much use for them in the first place, and nothing is using them any more, kill them off the rest of the way. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate pcibios_setup() in pci-lib.Paul Mundt2009-04-20
| | | | | | | This wasn't really being used for anything useful, so just stub it in pci-lib. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Flag the dreamcast BBA as IORESOURCE_PCI_FIXED.Paul Mundt2009-04-20
| | | | | | | This isn't a real BAR, so prevent any attempts to move it, as we don't wish to encourage a bus luck by overzealous PCI initialization code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off superfluous lboxre2 pci fixups.Paul Mundt2009-04-20
| | | | | | This is a verbatim copy of the r2d one, use that instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off the now unused hose->io_base.Paul Mundt2009-04-20
| | | | | | Nothing is using this any more, so kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate the remaining common bits.Paul Mundt2009-04-20
| | | | | | | | | | | 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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate bus<->resource mapping in pci-lib.Paul Mundt2009-04-20
| | | | | | | | Now that the io and mem offsets are tracked accordingly, the pci-new version of the bus<->resource mappers can be used generically. This moves them in to pci-lib. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Track io and mem_offset per-channel.Paul Mundt2009-04-20
| | | | | | This implements a per-hose offset for I/O and mem resources. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: New-style controller registration.Paul Mundt2009-04-20
| | | | | | | | 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 Mundt2009-04-20
| | | | | | | | | | | 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 Mundt2009-04-20
| | | | | | | This is left over cruft that hasn't been used by anything in a long time, kill off bits that weren't purged previously. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate pcibios_align_resource() definitions.Paul Mundt2009-04-20
| | | | | | | | This introduces a saner pcibios_align_resource() that can be used regardless of whether pci-auto or pci-new are being used, and consolidates it in pci-lib.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: HAVE_PCI_MMAP support.Paul Mundt2009-04-20
| | | | | | Derived from the MIPS version, now uses pgprot_noncached(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Split out new-style PCI core.Paul Mundt2009-04-20
| | | | | | | This splits off a 'pci-new.c' which is aimed at gradually replacing the pci-auto backend and the arch/sh/drivers/pci/pci.c core respectively. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Drop asm-generic/pci.h, so we can use our own fixups.Paul Mundt2009-04-20
| | | | | | | The new PCI code wants its own bus<->resource mappings instead of the generic equivalents, so drop the asm-generic include in preparation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Start unifying the SH7780 PCIC initialization.Paul Mundt2009-04-17
| | | | | | | This starts moving out the common initialization bits from the various fixup paths in to the shared init path. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate SH7780 PCIC IRQ routing.Paul Mundt2009-04-17
| | | | | | | | Now that the platform code is a bit leaner, we can start consolidating the various IRQ routing implementations. There are effectively only 2 variants, and the others can use those directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off platform-specific multi-window mappings.Paul Mundt2009-04-17
| | | | | | | | | | | Commit 68b42d1b548be1840aff7122fdebeb804daf0fa3 ("sh: sh7785lcr: Map whole PCI address space.") changed around the semantics of how various chip-selects are made accessible to PCI. Now that there is a single large mapping covering from CS0-CS6, there is no longer any need to do multi-window mapping. Subsequently, all of the differing implementations can be consolidated in to pci-sh7780. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Consolidate PCI I/O and mem window definitions for SH7780.Paul Mundt2009-04-17
| | | | | | | | This consolidates all of the PCI I/O and memory window definitions across the pci-sh7780 users in pci-sh7780 itself. No functional changes, in that every platform had exactly the same implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Set the I/O port base to the SH7780 I/O window default.Paul Mundt2009-04-17
| | | | | | | Presently the I/O port base isn't being set anywhere, which allows things like generic_inl() to blow up. Fix this up to point at the PCI IO window. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Set pci_cache_line_size on SH7780 via the PCICLS register.Paul Mundt2009-04-17
| | | | | | | | The SH7780 PCIC contains a read-only cache line size register that we can derive pci_cache_line_size from. So, make sure that the software idea of the cache line size actually matches the host controller's idea. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Use the proper write size for class/sub-class code.Paul Mundt2009-04-17
| | | | | | | Don't use pci_write_reg() for these, as it defaults to 32-bit. Rather than using the helper, use __raw_writeb() directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Rework SH7780 host controller detection.Paul Mundt2009-04-17
| | | | | | | | | | | | This reworks how the host controller is probed, and makes it a bit more verbose in the event a new type of controller is detected. Additionally, we also log the revision information. This now uses the proper access sizes for the vendor/device registers, rather than relying on a larger access that encapsulated both of them. Not all devices support 32-bit read cycles for these registers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Set class/sub-class code correctly for SH7780 PCIC.Paul Mundt2009-04-17
| | | | | | | | | | | | | The SH7780 PCI host controller implements a configuration header that requires a fair bit of hand-holding to initialize properly. By default it appears as a pre-2.0 host controller given the zeroed out class code, so fix this up properly. Some boards that happened to be using the R7780RP version of the PCIC fixups had set this correctly, but this belongs in the standard initialization, and is by no means board specific. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Prefer P1SEG over P1SEGADDR for CONFIG_CMD.Paul Mundt2009-04-17
| | | | | | | P1SEGADDR is obsolete and will be killed off completely in the future, so transition off of it and reference P1SEG explicitly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Move se7780 INTC fixups out of pci-sh7780.c.Paul Mundt2009-04-17
| | | | | | | These fixups belong in the board INTC setup code, not in the middle of pci-sh7780.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off useless debugging printk() in pci-sh7780 init.Paul Mundt2009-04-16
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: Kill off unused SH4_PCIC_NO_RESET code.Paul Mundt2009-04-16
| | | | | | Nothing ended up using this anymore, so just kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci: drop duplicate PCIC fixups for SE7780 and SH7785LCR.Paul Mundt2009-04-16
| | | | | | | SE7780 has the same PCIC fixup as SDK7780, and SH7785LCR the same as R7780RP. Switch to using those, and drop the duplicate code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: sh7785lcr: Update for recent PCI changes.Paul Mundt2009-04-16

* sh: drop duplicate symbol export on dreamcast and sh7785lcr.Paul Mundt2009-04-16
| | | | | | | With board_pci_channels now being exported in a single place, update the boards that duplicated the export. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: export board_pci_channels in one placeMagnus Damm2009-04-16
| | | | | | | | Instead of sometimes exporting board_pci_channels[] in the board specific code just export it in one place. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci io port base address codeMagnus Damm2009-04-16
| | | | | | | | | | Adds a __get_pci_io_base() function which is used to match a port range against struct pci_channel. This allows us to detect if a port range is assigned to pci or happens to be legacy port io. While at it, remove unused cpu-specific cruft. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: pci memory range checking codeMagnus Damm2009-04-16
| | | | | | | | | This patch changes the code to use __is_pci_memory() instead of is_pci_memaddr(). __is_pci_memory() loops through all the pci channels on the system to match memory windows. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: add io_base member to pci_channelMagnus Damm2009-04-16
| | | | | | | | Store the io window base address in struct pci_channel and use that one instead of SH77xx_PCI_IO_BASE. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
