9068a4c646 USB: pxa2xx_udc: use generic gpio layer
This patch lets the pxa2xx_udc use the generic gpio layer,
on the relevant PXA and IXP systems.

dcdeeb21c0 [ARM] 4426/2: Netgear WG302 v2 and WAG302 v2 support
This patch provides support for the Netgear WG302 v2 and WAG302 v2 AccessPoint series.

This patch relies on the patch "Gateway 7001 series support" minimally, as they only have UART2 connected.

3603ab2b62 [ARM] mm 10: allow memory type to be specified with ioremap
__ioremap() took a set of page table flags (specifically the cacheable
and bufferable bits) to control the mapping type.  However, with
the advent of ARMv6, this is far too limited.

Replace the page table flags with a memory type index, so that the
desired attributes can be selected from the mem_type table.

Finally, to prevent silent miscompilation due to the differing
arguments, rename the __ioremap() and __ioremap_pfn() functions.

This is an ARM XScale IXP4xx system relatively similar to

important difference is Gigabit Ethernet support using
the Via Velocity chipset.

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

f80dff9da0 [ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user
get_irqnr_preamble allows machines to take some action before entering the
get_irqnr_and_base loop.  On iop we enable cp6 access.

arch_ret_to_user is added to the userspace return path to allow individual
architectures to take actions, like disabling coprocessor access, before
the final return to userspace.

Per Nicolas Pitre's note, there is no need to cp_wait on the return to user
as the latency to return is sufficient.

4ec031166f [PATCH] kill eth_io_copy_and_sum()
On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len).
The function name is highly misguiding (it _never_ does any checksums), the
last argument is just a noise and simply expanding the call to memcpy_fromio()
gives shorter and more readable source.  For a lot of reasons it has almost
no remaining users, so it's better to just outright kill it.

32f3f49910 [ARM] 4141/1: consolidate functions that handles gpio in pxa2xx_udc
This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get.

These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h

Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions.

Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq).

This is next step to make pxa2xx_udc fully work on ixp4xx platform.

76bbb00288 [ARM] 3487/1: IXP4xx: Support non-PCI systems
Patch from Deepak Saxena

This patch allows for the addition of IXP4xx systems that do not make
use of the PCI interface by moving the CONFIG_PCI symbol selection to
be platform-specific instead of for all of IXP4xx. If at least one machine
with PCI support is built, the PCI code will be compiled in, but when
building !PCI, this will drastically shrink the kernel size.

macros every time.  Provide a common implementation and convert these
implementations to use this version.

411ef7f4cf [ARM] Remove asm/arch/irq.h
asm/arch/irq.h used to be included from asm/irq.h, but was removed
from the ARM kernel a long time ago.  Consequently, the contents
of asm/arch/irq.h (which mostly contain a definition for fixup_irq())
have not been used.  Hence, remove asm/arch/irq.h.

Some machine support files incorrectly included this file, making
little or no use of the contents.  Move the contents to a local
include file, and remove those include statements as well.

Patch from Alessandro Zummo

The I2C pin assignment for the Iomega NAS100d board was incorrect.  This
patch fixes it.  The correct assignment has now been tested using the
new RTC class and a new driver for the RTC on the NAS100d.

54e269ead6 [ARM] 3226/1: IXP4xx runtime expansion bus window size configuration
Patch from Deepak Saxena

The expansion bus on the IXP46x NPU can be configured for either 32MiB or
16MiB windows and changing the configuration causes the base address for
each chip select for each region to change. Because of this, we cannot
hardcode the physical base as we currently do. This patch checks the
expansion bus configuration registers at runtime to determine the
appropriate window size. Note that this requires that the bootloader
already configured the device sizes appropriately, but I feel that is
valid assumption to make as the bootloader must configure and access
the flash window, the output display (LCD, LEDs, etc) window, and
other expansion bus devices.

313cbb5519 [ARM] 3218/1: PAGE_SHIFT undeclared in arch-ixp4xx/memory.h (adjust_zones moved out of line)

3145d8a6cc [ARM] 3215/1: Iomega NAS 100d (MACH_NAS100D) machine support
Patch from Rod Whitby

This patch adds support for a new arm/ixp4xx machine - the Iomega NAS 100d network attached storage product.  The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card.

Work on porting the latest 2.6.x kernel to this device is being done by
the NSLU2-Linux project (the same team who maintains the port to the
Linksys NSLU2 device).  In particular, the majority of this patch was
authored by Alessandro Zummo, based on the work done for MACH_NSLU2
support by the NSLU2-Linux core team of developers.

MACH_NAS100D (as implemented by this patch) can be enabled in jumbo
ixp4xx kernels without any affect on the other machines supported by
that kernel.

This patch applies cleanly against 2.6.15-rc7 and should be trivial to
apply to later kernel versions. It does not depend upon any other
patches.

Patch from Deepak Saxena

Other than interrupt masking purposes, this API is only used when
configuring interrupt lines and this patch moves that functionality
directly into the ixp4xx_set_irq_type() implementation as board level
PCI code should not need to worry about those details.

a7918f39bb [ARM] 3140/1: NSLU2 machine support
Patch from Alessandro Zummo

This patch adds support for the LinkSys NSLU2 running with
both big and little-endian kernels. The LinkSys NSLU2 is
a cost engineered ARM, XScale 420 based system similar to
the the Intel IXDP425 evaluation board. It uses the
IXP4XX ARCH.

While this patch applies independently of other patches
the resultant kernel requires further patches to successfully
use onboard devices, including the onboard flash. Since these
patches are independent of this one they will be submitted
separately.

A defconfig is not included here because not all of
the required drivers are actually in the kernel.
We intend to provide one as soon as the patches
will be incorporated in mainstream.

This patch is the combined work of nslu2-linux.org

bfca94590b [ARM] 3083/1: include/asm-arm/arch-ixp4xx/io.h: eliminate warnings for pointer passed to integral function argument
Patch from John Bowler

Fix for a compiler warning, this wasn't apparent in 2.6.12, I
believe the compiler options have been changed (somewhere) so
that passing a (void*) to a (u32) argument is now warned.

This accounts for the majority of the warnings in my builds of
the 2.6.14 kernel for NSLU2.

The patch changes pointer parameters declared as u32 to be
declared as either, for read parameters:

const volatile void __iomem *

and for write parameters:

volatile void __iomem *
