Current bootm implementation on ARM has the problem with systems with
much memory. The devicetree is allocated with malloc(). On some systems
the malloc area is outside of the kernels lowmem, so the kernel can't
access the devicetree anymore. The complexity of the current code
makes it hard to solve, so this series contains several patches to
make the bootm code simpler before the actual problem is solved.
