Our signal syscall restart handling for these kernels still uses
the userspace stack to build code for restarting the syscall.
Unfortunately, fixing this is non-trivial, and so for the time
being, we resolve the problem by disabling NX support.

Since commit eb0519b5a1cf, mv643xx_eth is non functional on ARM because
the platform device declaration does not include any coherent DMA mask
and coherent memory allocations fail.

Currently "tidspbridge" driver uses its own mmu implementation and
will migrate to use this "omap iommu" eventually. This config is
provided to make this migration happen smoothly.

Grrr. Some days it feels like all of the good names are already taken.
Let's just rename the two static users in arm and avr32 to get this

This patch provides a device drivers, which has a omap iommu, with
address mapping APIs between device virtual address(iommu), physical
address and MPU virtual address.
There are 4 possible patterns for iommu virtual address(iova/da) mapping.
|iova/ mapping iommu_ page
| da pa va (d)-(p)-(v) function type
---------------------------------------------------------------------------
1 | c c c 1 - 1 - 1 _kmap() / _kunmap() s
2 | c c,a c 1 - 1 - 1 _kmalloc()/ _kfree() s
3 | c d c 1 - n - 1 _vmap() / _vunmap() s
4 | c d,a c 1 - n - 1 _vmalloc()/ _vfree() n*
'iova': device iommu virtual address
'da': alias of 'iova'
'pa': physical address
'va': mpu virtual address
'c': contiguous memory area
'd': dicontiguous memory area
'a': anonymous memory allocation
'()': optional feature
'n': a normal page(4KB) size is used.
's': multiple iommu superpage(16MB, 1MB, 64KB, 4KB) size is used.
'*': not yet, but feasible.

The arch_initcall() is too late for board initialisation to use
gpiolib when doing their machine specific initilisation via the

This moves the GPIO driver away from using __devinit and __devexit
It also removes all printk() in favor of using dev_* print macros
on pdev->dev struct instead. Surplus prints are removed, and the
platform_device_probe() function is used instead of putting a
.probe function in the platform driver struct.

Add support for the DMA blocks in the S3C64XX series of CPUS,
which are based on the ARM PL080 PrimeCell system.
Unfortunately, these DMA controllers diverge from the PL080
design by adding another DMA controller register and
configuration for OneNAND.

Prepare to remove the large number of S3C2410_GPxn defines
by moving to S3C2410_GPx(n) in arch/arm.

The S3C24XX_GPIO_BASE makes it difficult to compress the
GPIO number space, and is only used in a few places of
which everything outside arch/arm/plat-s3c24xx/gpiolib.c
will be removed as soon as possible.
Change gpiolib.c to use the S3C2410_GPxCON register addresses
as the base for each bank, thus eliminating S3C24XX_GPIO_BASE.

The <mach/regs-gpio.h> really does not need the input and output
pin configurations as these are standard and have a generic
representation (plus the s3c24xx gpio specific code is going to
be phased out soon).
The following sed was applied to remove the lines:
sed -i~ -e '/S3C2410_GP[A-Z][0-9]*_\INP/d' \
-e '/S3C2410_GP[A-Z][0-9]*_\OUTP/d' \
-e '/S3C2410_GPA[0-9]*_OUT/d'
to remove these.

Move all the gpio functions out of <mach/hardware.h> as
this file is for defining the generic IO base addresses
for the kernel IO calls.
Make a new header <mach/gpio-fns.h> to take this and
include it via the chain from <linux/gpio.h> which is
what most of these files should be using (and will be
changed as soon as possible).
Note, this does make minor changes to some drivers but
should not mess up any pending merges.

'mach-pxa' platforms currently rely on a bootloader to setup GPIO pins
and clear RDH (to enable inputs).
A kernel loaded by a 'minimal' bootloader, that doesn't touch any pins,
will not function correctly; inputs will remain disabled, even after the
pins are configured. The following change fixes the issue and has been
verified on Gumstix Verdex XL6P and a custom PXA270 platform.
