omap3 has a soc specific reset function, make sure it calls common_reset
so that the proper CPU flags are set.

putc already is a regular barebox function. To avoid conflicts and
confusions just let architectures define PUTC_LL directly instead
of going through this addiotional redirection.

structure is used within barebox only and there is no need to pack it.
As this option has a negative performance impact, remove it.

Needed so that the linker can throw it away when unused. This is needed
at least on current master for being able to enable pbl support for omap3
boards.

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.
