This patch introduces the Openmoko GTA02 machine definition.
Much of the code is based on Harald Welte's work, although it
has been largely rewritten several times.
This is intended to be the minimum machine definition to boot and
be able to run a rootfs from NAND on GTA02 / FreeRunner. It does
not bring up the framebuffer / Glamo and lacks many other peripheral
drivers from outside the SoC. But once we have this basis in
mainline kernel, we will be able to introduce the other drivers
and add them here.
Thanks to Sven Rebhan <odinshorse@googlemail.com> for his fixes to this
patch (Kconfig and defconfig files).

This patch provides initial support for CPU frequency scaling on the
Samsung S3C ARM processors. Currently only S3C6410 processors are
supported, though addition of another data table with supported clock
rates should be sufficient to enable support for further CPUs.
Use the regulator framework to provide optional support for DVFS in
the S3C cpufreq driver. When a software controllable regulator is
configured the driver will use it to lower the supply voltage when
running at a lower frequency, giving improved power savings.
When regulator support is disabled or no regulator can be obtained
for VDDARM the driver will fall back to scaling only the frequency.

Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.

On this board, the PXA272 CPU voltage VCC_CORE is provided
by a Maxim 1586 voltage regulator. Use the regulator
framework to provide VCC_CORE control. When cpufreq will be
updated to ask for vcc_core, this will optimize power
drained by the board.

This provides a reliable way for asm-generic/types.h and other
files to find out if it is running on a 32 or 64 bit platform.
We cannot use CONFIG_64BIT for this in headers that are included
from user space because CONFIG symbols are not available there.
We also cannot do it inside of asm/types.h because some headers
need the word size but cannot include types.h.
The solution is to introduce a new header <asm/bitsperlong.h>
that defines both __BITS_PER_LONG for user space and
BITS_PER_LONG for usage in the kernel. The asm-generic
version falls back to 32 bit unless the architecture overrides
it, which I did for all 64 bit platforms.
