The old way to boot tiny210 was to restart barebox after loading stage2 image.
This turned out to be unstable and stopped working after barebox refactoring.
Now jump to the same position in the loaded code instead of starting it from
the very beginning.

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.

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>.
