e55823492d PCI: sh: use generic INTx swizzle from PCI core
Use the generic pci_common_swizzle() instead of arch-specific code.

Note that pci_common_swizzle() loops based on dev->bus->self, not
dev->bus->parent as the sh simple_swizzle() did.  I think they
are equivalent for this purpose.

0aea531326 PCI: remove unused arch pcibios_update_resource() functions
Russell King did the following back in 2003:

<--  snip  -->

    [PCI] pci-9: Kill per-architecture pcibios_update_resource()

    Kill pcibios_update_resource(), replacing it with pci_update_resource().
    pci_update_resource() uses pcibios_resource_to_bus() to convert a
    resource to a device BAR - the transformation should be exactly the
    same as the transformation used for the PCI bridges.

    pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
    set the high 32-bits to anything non-zero - currently no architecture
    attempts to do something different.  If anyone cares, please fix; I'm
    going to reflect current behaviour for the time being.

    Ivan pointed out the following architectures need to examine their
    pcibios_update_resource() implementation - they should make sure that
    this new implementation does the right thing.  #warning's have been
    added where appropriate.

        ia64
        mips
        mips64

    This cset also includes a fix for the problem reported by AKPM where
    64-bit arch compilers complain about the resource mask being placed
    in a u32.

<--  snip  -->

This patch removes the unused pcibios_update_resource() functions the
kernel gained since, from FRV, m68k, mips & sh architectures.

b70d3a2c59 iomap: fix 64 bits resources on 32 bits
Almost all implementations of pci_iomap() in the kernel, including the generic
lib/iomap.c one, copies the content of a struct resource into unsigned long's
which will break on 32 bits platforms with 64 bits resources.

This fixes all definitions of pci_iomap() to use resource_size_t.  I also
"fixed" the 64bits arch for consistency.

1ba6ab11d8 PCI: remove initial bios sort of PCI devices on x86
We currently keep 2 lists of PCI devices in the system, one in the
driver core, and one all on its own.  This second list is sorted at boot
time, in "BIOS" order, to try to remain compatible with older kernels
(2.2 and earlier days).  There was also a "nosort" option to turn this
sorting off, to remain compatible with even older kernel versions, but
that just ends up being what we have been doing from 2.5 days...

Unfortunately, the second list of devices is not really ever used to 
determine the probing order of PCI devices or drivers[1].  That is done
using the driver core list instead.  This change happened back in the
early 2.5 days.

Relying on BIOS ording for the binding of drivers to specific device
names is problematic for many reasons, and userspace tools like udev
exist to properly name devices in a persistant manner if that is needed,
no reliance on the BIOS is needed.

Matt Domsch and others at Dell noticed this back in 2006, and added a
boot option to sort the PCI device lists (both of them) in a
breadth-first manner to help remain compatible with the 2.4 order, if
needed for any reason.  This option is not going away, as some systems
rely on them.

This patch removes the sorting of the internal PCI device list in "BIOS"
mode, as it's not needed at all anymore, and hasn't for many years.
I've also removed the PCI flags for this from some other arches that for
some reason defined them, but never used them.

This should not change the ordering of any drivers or device probing.

[1] The old-style pci_get_device and pci_find_device() still used this
sorting order, but there are very few drivers that use these functions,
as they are deprecated for use in this manner.  If for some reason, a
driver rely on the order and uses these functions, the breadth-first
boot option will resolve any problem.

da2d7f4bc5 sh: update r7780rp interrupt code
This patch updates the board specific irq code for r7780rp. The new code is
very similar to the other highlander implementations, with the exception that
the r7780rp handles pci interrupts using IRL. To simplify the pci code and
use the same interrupt numbers as r7780mp and r7785rp we hook in to the
cpu specific pci vectors.

The pci interrupts and the push switch all work well with and without this
patch. CF and AX88796 are not ok though and the source of the problem is
unknown at this point. The AX88796 does for not detect it's proper mac
address (IPL gets it right) and the kernel hangs on CF access. As a workaround
this patch removes the CF and the AX88796 from the platform datain case of
r7780rp.

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized

MIPS low level cache API exported to the entire world.  The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync.  So
remove it rsp.  turn the surviving bits back into an arch private API, as

This patch converts the board specific interrupt code for r2d to make
use of intc. While at it we improve the Kconfig to avoid confusion.

- Two sets of interrupt tables exist - one for R2D-1 and one for R2D-PLUS.
- R2D-1 and R2D-PLUS use the same irq constants.
- R2D-1 has AX88796 support, R2D-PLUS does not hook up that IRQ.
- R2D-PLUS has KEY support, R2D-1 does not hook up that IRQ.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 100.
- The machvec demux function converts from irlm IRQ 0-14 to IRQ 100++.

Tested on R2D-1 and R2D-PLUS boards.

Version 2 adds CONFIG_RTS7751R2D_1 and CONFIG_RTS7751R2D_PLUS together
with intc structured as __initdata.

                bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size;
...
                *lower_limit = bar_value + bar_size;
}

As a result, 0x4000000 is set in *lower_limit, but this value is wrong.

The following patch avoids this problem by checking the range of the
value and refusing to update the BAR if the calculated value ends up
being bogus.

e65fa9f59e sh: Kill off dead bigsur and ec3104 boards.
Neither of these have had any maintenance in years, and there's
no interest in keeping them straggling along. These have already
been slated for removal some time, so finally just get rid of them.

ea0f8feaa0 sh: sh775x/titan fixes for irq header changes.
The following moves the creation of IPR interupts into setup-7750.c
and updates a few other things to make it all work after the "Drop
CPU subtype IRQ headers" commit. It boots and runs fine on my titan
board.

 - adds an ipr_idx to the ipr_data and uses a function in the subtype
   code to calculate the address of the IPR registers

 - adds a function to enable individual interrupt mode for externals
   in the subtype code and calls that from the titan board code
   instead of doing it directly.

 - I changed the shift in the ipr_data to be the actual # of bits to
   shift, instead of the numnber / 4 - made it easier to match with
   the manual.

9a7ef6d59f sh: Drop CPU subtype IRQ headers.
This drops the various IRQ headers that were floating around
and primarily providing hardcoded IRQ definitions for the
various CPU subtypes. This quickly got to be an unmaintainable
mess, made even more evident by the subtle breakage introduced
by the SH-2 and SH-2A changes.

Now that subtypes are able to register IRQ maps directly, just
rip all of the headers out.

082c44d20e sh: Cleanup board header directories.
Now with the ide.h mess sorted out, most of these boards
don't need their own directory. Move the headers out, and
update the driver paths.
