omap_save_bootinfo derefences the argument passed to barebox without
checking it for validity. This breaks 2nd stage booting where r0
is undefined. The best we can do is to check whether the pointer is
somewhere in SRAM and is word aligned. This at least makes sure that
we do not oops. This introduces SoC specific xxx_save_bootinfo variants
since the SRAM addresses/sizes differ between SoCs.
Additionally fix the prototype for omap_save_bootinfo. It uses r0, so
it must be passed this variable.

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().

The ROM loader passes the address of a buffer to the MLO in
register 0. Store this data so we can find the boot source later.
On the same way the bootinformation are passed to the barebox,
then. It has to be enshured that r0 contains always the
buffer or the boot source detection will not work.
Applied this on all OMAPs. This patch is based on work of
Jan Luebbe <jlu@pengutronix.de>.

Having the board config file in /env/init has the problem that

All boards use hardcoded SDRAM addresses, copied from the board init file.

We now have gpio_request. When we call gpio_direction_output before
registering a led_gpio the gpio will be implicitely requested by the
gpio core. gpio_request in the led core will then fail resulting in
an unregistered LED.
Fix this by removing the call to gpio_direction_output. The LED core
will do this anyway.

On some SoCs (for example AM35xx), the ROM bootloader passes useful
information in r0 when jumping to barebox.
To avoid overwriting this in the generic reset code, we introduce
common_reset as a C function and as an assembler macro. This is then
called form the reset entry point (either in common or in board code).

This is because the USBHOST module is not enabled. The module enable
is is normally done in mach-omap/xload.c which never gets called.
Since we're configuring the USBHOST CLKCTRL register in the board file
anyway, we might as well explicitly enable the module in the same place.

Currently, there are multiple definitions of run_shell()
for each board that can be build in "xload" configuration.
Now there is only one function used by all boards.
The functions defined in xload.c are used only when "xload"
