Fix the NAND flash timings on the AT91SAM9260.

The current timings lead to the detection of a number of bad blocks.
These timings are now set the same as on the AT91SAM9263.

094f127588 [ARM] 4271/1: iop32x: fix ep80219 detection (support iq80219 platforms)
An iq80219 is a board with an iq31244 layout and an 80219 processor.  It
breaks the current assumption that all 80219 processors run on ep80219
platforms.  This patch adds the "force_ep80219" option to the kernel to
override boot loaders that have passed in the iq31244 id, and adds the
MACHINE_START definition for ep80219.

28735a7253 [PATCH] gpio_direction_output() needs an initial value
It's been pointed out that output GPIOs should have an initial value, to
avoid signal glitching ...  among other things, it can be some time before
a driver is ready.  This patch corrects that oversight, fixing

 - documentation
 - platforms supporting the GPIO interface
 - users of that call (just one for now, others are pending)

There's only one user of this call for now since most platforms are still
using non-generic GPIO setup code, which in most cases already couples the
initial value with its "set output mode" request.

Note that most platforms are clear about the hardware letting the output
value be set before the pin direction is changed, but the s3c241x docs are
vague on that topic ...  so those chips might not avoid the glitches.

0a938b9768 [PATCH] add CONFIG_GENERIC_GPIO
Most drivers using GPIOs already know they are running on a system that
supports the generic GPIO calls, because of other platform dependencies.
But the generic GPIO-based LED and input button drivers can't know that.

So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms
where <asm/gpio.h> will do the right thing.  Currently that's a bunch of
ARMs, and AVR32; more are on the way.

It also fixes a dependency bug for the gpio button input driver; it was
wrong to start with, now it covers all platforms with GENERIC_GPIO.

ec3622d963 [ARM] 4226/1: initial .data and .bss mappings of XIP kernel should be TEXT_OFFSET
aware

Since TEXT_OFFSET is meant to determine RAM location for kernel use,
itshould affect .data and .bss initial mapping in the XIP case.
Otherwise a XIP kernel would crash if TEXT_OFFSET gets somewhat larger
than 2MB.

Corresponding code is also moved up a bit to be near the similar .text
mapping code making the whole a bit more straight forward to understand.

e98ff7f6d8 [ARM] 4224/2: allow XIP kernel to boot again
Since commit 2552fc27ff XIP kernels failed
to boot because (_end - PAGE_OFFSET - 1) is much smaller than the size
of the kernel text and data in the XIP case, causing the kernel not to
be entirely mapped.

Even in the non-XIP case, the use of (_end - PAGE_OFFSET - 1) is wrong
because it produces a too large value if TEXT_OFFSET is larger than 1MB.

Finally the original code was performing one loop too many.

Let's break the loop when the section pointer has passed the last byte
of the kernel instead.

Fix 3 small typo's - two in comments, and the incorrect clock was
specified for the LCD device.
