The header magic is a bit odd, but similar to the KERNEL_DS

When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2
divider, add a short delay before returning to SDRAM to allow the SDRC
time to stabilize. Without this delay, the system is prone to random
panics upon re-entering SDRAM.
This time delay varies based on MPU frequency. At 500MHz MPU frequency at
room temperature, 64 loops seems to work okay; so add another 32 loops for
environmental and process variation.

Add alignment fault fixup support for 32-bit Thumb-2 LDM, LDRD, POP,
PUSH, STM and STRD instructions. Alignment fault fixup support for
the remaining 32-bit Thumb-2 load/store instruction cases is not
included since ARMv6 and later processors include hardware support
for loads and stores of unaligned words and halfwords.

Manually fix up conflicts due to kmemcheck in mm/slab.c
* create mm/init-mm.c, move init_mm there
* remove INIT_MM, initialize init_mm with C99 initializer
* unexport init_mm on all arches:
init_mm is already unexported on x86.
One strange place is some OMAP driver (drivers/video/omap/) which
won't build modular, but it's already wants get_vm_area() export.
Somebody should look there.

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).

[ben-linux@fluff.org: Fix the GPIO definitions]

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.
