This replaces the reset_cpu() function which every SoC or board must
provide with registered handlers. This makes it possible to have multiple
reset functions for boards which have multiple ways to reset the machine.
Also boards which have no way at all to reset the machine no longer
have to provide a dummy reset_cpu() function.
The problem this solves is that some machines have external PMICs or
similar to reset the system which have to be preferred over the
internal SoC reset, because the PMIC can reset not only the SoC but also
the external devices.
To pick the right way to reset a machine each handler has a priority. The
default priority is 100 and all currently existing restart handlers are
registered with this priority. of_get_restart_priority() allows to retrieve
the priority from the device tree which makes it possible for boards to
give certain restart handlers a higher priority in order to use this one
instead of the default one.

Since we no longer have custom gpio function prototypes we can
drop the prototypes from asm-generic/gpio.h can add them to
include/gpio.h instead. While at it add static inline dummy wrappers
for !CONFIG_GENERIC_GPIO so that code using gpios can compile without
gpio support.

This was broken in 558d72dc51 (ARM Samsung: fix booting from NAND with
pbl). '_text' is TEXT_BASE when building without pbl and (TEXT_BASE -
SZ_2M) when building with pbl, so this works in both cases.

The ARM pbl is linked at (TEXT_BASE - SZ_2M). This conflicts with the temporary
stack used in s3c24x0_nand_boot. Moving the stack to (TEXT_BASE - SZ_2M) fixes
this problem. With this patch a compressed barebox with pbl can boot on
mini2440 from NAND.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.
Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

All Samsung boards automatically detect their SDRAM size. The size detection
code can't be called safely from lowlevel C code, so instead the minimum SDRAM
size is guessed from the defconfig files.

The S3C64XX SoC has a real 32 bit counter, but almost the same style of

this SoC.

Barebox crashes since it has trouble with a resource size of 0. Most of the
S3C24XX based platforms crashes at runtime and can't use devices with resource
sizes of 0 anymore. This patch fix it by unifying the device registration for
all current Barebox's S3C24XX based platforms.

Ok, I assume this should go into separate series. It fits both S5PV210 and S3C6410.
This adds support for S3C and S5P architectures (all of my knowledge) to the
serial driver. Since the only difference between them is in clock handling,
this is moved to an arch-dependent separate function.
Most modern architectures should define S3C_UART_HAS_UBRDIVSLOT and S3C_UART_HAS_UINTM.
This adds support for most
