2009-04-26sh: convert to use __HEAD and HEAD_TEXT macros.Tim Abbott4-4/+8
This has the consequence of changing the section name use for head code from ".text.head" to ".head.text". Since this commit changes all users in the architecture, this change should be harmless.

2009-04-21sh: Fix mmap2 for handling differing PAGE_SIZEs.Toshinobu Sugioka1-0/+9
mmap2 uses a fixed page shift of 12, regardless of the PAGE_SIZE setting. Fix up the mmap2 code to add some sanity checks on the mapping, and to update pgoff accordingly. Error handling bits based on 4280e3126f641898f0ed1a931645373d3489e2a6 ("frv: fix mmap2 error handling").

2009-04-20sh: pci: Rename pci-new.c to pci.c.Paul Mundt3-5/+1
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>
2009-04-20sh: pci: Roll pci-lib in to pci-new.Paul Mundt3-225/+221
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>

2009-04-20sh: pci: Move the se7751 fixups in to arch/sh/drivers/pci/.Paul Mundt4-152/+112
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>

2009-04-20sh: pci: Rename SH7751 platform ops files to fixups.Paul Mundt5-4/+4
None of these contain pci_ops, only IRQ routing bits, rename them accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Rewrite SH7751 PCI support to follow SH7780.Paul Mundt10-305/+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>
2009-04-20sh: pci: Rename ops-cayman -> fixups-cayman.Paul Mundt2-1/+1
Now that ops-cayman.c only contains IRQ routing fixups, rename it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-04-20sh: pci: Kill off legacy ide quirks.Paul Mundt2-42/+0
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>
2009-04-20sh: pci: Consolidate pcibios_setup() in pci-lib.Paul Mundt4-35/+16
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>
2009-04-20sh: pci: Kill off dead references to is_pci_ioaddr and friends.Paul Mundt4-66/+0
Some old boards are still using this in their I/O routines, kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Flag the dreamcast BBA as IORESOURCE_PCI_FIXED.Paul Mundt1-0/+7
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>
2009-04-20sh: pci: Kill off superfluous lboxre2 pci fixups.Paul Mundt2-43/+1
This is a verbatim copy of the r2d one, use that instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Kill off the now unused hose->io_base.Paul Mundt3-10/+0
Nothing is using this any more, so kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Consolidate the remaining common bits.Paul Mundt3-116/+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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Consolidate bus<->resource mapping in pci-lib.Paul Mundt3-45/+31
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>
2009-04-20sh: pci: Track io and mem_offset per-channel.Paul Mundt3-9/+14
This implements a per-hose offset for I/O and mem resources. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: New-style controller registration.Paul Mundt3-83/+130
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>
2009-04-20sh: pci: Rework fixed region checks in ioremap().Paul Mundt2-25/+18
Not all PCI channels have non-translatable memory windows, this is a special property of the on-chip PCIC with its 0xfd00... mapping, handle this explicitly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Consolidate pci_iomap() and use the generic I/O base.Paul Mundt5-94/+53
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>
2009-04-20sh: pci: Kill off unused pcibios_fixup().Paul Mundt2-6/+0
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>
2009-04-20sh: pci: Consolidate pcibios_align_resource() definitions.Paul Mundt5-53/+49
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>
2009-04-20sh: pci: HAVE_PCI_MMAP support.Paul Mundt3-3/+32
Derived from the MIPS version, now uses pgprot_noncached(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-20sh: pci: Split out new-style PCI core.Paul Mundt3-4/+258
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>
2009-04-20sh: pci: Drop asm-generic/pci.h, so we can use our own fixups.Paul Mundt2-3/+38
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>
2009-04-19sh: sh7724: Register CMT as an early platform device here too.Paul Mundt1-0/+10

2009-04-19sh: arch earlytimer supportMagnus Damm1-0/+9
Extend the 32-bit SuperH timer code to register and probe the earlytimer class of Early Platform Drivers. This registers the sh_cmt driver if compiled-in. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-17sh: pci: Start unifying the SH7780 PCIC initialization.Paul Mundt4-70/+37
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>
2009-04-17sh: pci: Consolidate SH7780 PCIC IRQ routing.Paul Mundt7-137/+31
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>
2009-04-17sh: pci: Kill off platform-specific multi-window mappings.Paul Mundt7-95/+33
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>
2009-04-17sh: pci: Consolidate PCI I/O and mem window definitions for SH7780.Paul Mundt6-90/+27
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>
2009-04-17sh: pci: Set the I/O port base to the SH7780 I/O window default.Paul Mundt1-0/+2
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>
2009-04-17sh: pci: Set pci_cache_line_size on SH7780 via the PCICLS register.Paul Mundt1-9/+12
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>
2009-04-17sh: pci: Use the proper write size for class/sub-class code.Paul Mundt1-2/+4
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>
