The code which makes up the zImage header intends to leave a 32-byte gap followed by a branch to the real entry point, a magic number, and a word containing the absolute entry point address. This gets messed up with with CONFIG_THUMB2_KERNEL, because the size of the initial padding NOPs changes. Instead, the header can be made fully compatible by restoring it to ARM. In the Thumb-2 case, we can replace the initial NOPs with a sequence which switches to Thumb and jumps to the real entry point. As a consequence, the zImage entry point is now always ARM, so no special magic is needed any more for the uImage rules in the Thumb-2 case.
