When the board is on console, a way is added to manually power off the
board, on a long power key press (4s).
This enables to be able to poweroff the board whatever the state, and is

As barebox has grown up in size, because UBI support is now embedded in
barebox, and because the IPL is at least rewritten to be fully GPL,
modify mioa701 support to take into account this new layout :
- IPL is version 0.5
- MTD layout is fully changed
- the boot sequence is rewritten :
- the volume up button triggers console mode
- upon PowerOn or Sleep exit, power key is debounced and if not
help board is powered off back
- sdcard environment override can now stop the autoboot sequence
- mtd environment override can now stop the autoboot sequence

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
