powerpc/kexec: Add support for FSL-BookE
This adds support kexec on FSL-BookE where the MMU can not be simply switched off. The code borrows the initial MMU-setup code to create the identical mapping mapping. The only difference to the original boot code is the size of the mapping(s) and the executeable address. The kexec code maps the first 2 GiB of memory in 256 MiB steps. This should work also on e500v1 boxes. SMP support is still not available. (Kumar: Added minor change to build to ifdef CONFIG_PPC_STD_MMU_64 some code that was PPC64 specific) Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
