All boards use hardcoded SDRAM addresses, copied from the board init file.
OMAP3 boards are a bit special, they had a SoC specific reset() function. This
is renamed to omap3_invalidate_dcache() and called from the board lowlevel init
code now.

Currently Kconfig dependencies are used to allow non-interactive builds.
This leads to problems in Kconfig getting the dependencies right.
This patch adds a barebox_main function pointer which is called at the
end of the startup process. This defaults to run_shell when a shell is
enabled.
With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive
builds can now be enabled for every board allowing to compile a binary
without further Kconfig dependencies. This also allows for more flexibility,
for example boards may decide to try non-interactive startup first and
call run_shell if that fails.

Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:
- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian
The mk-am35xx-spi-image tool converts barebox.bin to
this format.

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>.

OMAP3 is the only architecture which has a arch_init_lowlevel in
which it invalidates the dcache. This can easily be done in
board_init_lowlevel aswell. Since on OMAP3 we are always executed
in SRAM we'll never need a board specific lowlevel_init. So the
easiest way of getting rid of this special handling is to just
rename the function.

Remove what is an apparently valueless Kconfig variable HAS_OMAP_NAND.
A search of the entire source tree shows:
$ grep -r HAS_OMAP_NAND *
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig:config HAS_OMAP_NAND
arch/arm/configs/phycard_a_l1_defconfig:CONFIG_HAS_OMAP_NAND=y
$
where the definition of that variable is simply:
config HAS_OMAP_NAND
bool
so it seems pretty clear it can be removed as nothing is using it.
