[PATCH] Thumb2 support

[Sascha Hauer]

Add some preparation to support Thumb2 support and finally Thumb2
support itself.

Sascha Hauer (3):
      ARM: move exception vectors away from start of binary
      ARM: get runtime offset of board_init_lowlevel_return by using separate section
      ARM: Allow to compile in thumb-2 mode
