Which bootmode is selected has no longer to be chosen by Kconfig. The
boards can decide themselves which bootmode they want to support. This
makes it unnecesary to ask the user which bootmode shall be supported,
so the "Select boot mode" becomes invisible and both support will be
compiled in as needed by the boards. NAND_IMX_BOOT goes away and the
already existing ARCH_IMX_EXTERNAL_BOOT_NAND can now be used for the
boards to depend on external nand boot.

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().

Most i.MX boards can use the imx*_barebox_entry functions. The remaining
(i.MX21, i.MX6) use hardcoded base addresses.

Several i.MX boards setup a temporary stack in their lowlevel code.
Instead of using STACK_BASE use a stack in internal SRAM to get rid
of the STACK_BASE compile time dependency.

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 patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

With compressed image support TEXT_BASE will become the base
address of the uncompressed image. What the boards want instead
is the base address of the decompressor code or, if not compressed,
the base address of the uncompressed image. Use _text which is
the correct one for both cases.

The new MMU setup will need SDRAM base addresses and sizes.
For this reason convert the MMU enabled ARM boards:

Often enough the exception vectors are not on TEXT_BASE (for example
on i.MX SoCs in internal boot mode), so the board specific code did
not map the exception vectors to 0x0 but whatever happens to be on
TEXT_BASE. Also, the current section-only mapping requires the
exception vectors to be on a 1MB boundary.
Instead, create the possibility to create second level tables and
use this to map a copy of the exception vectors in a board
independent way.
