I came across the following issue while testing Kdump on an SMP

the device-tree has the nodes for second CPU and the related details.
The kexec tool adds the spin table area as a reserved section in the

the hardware/qemu/simics work fine.
This patch is harmless and initializes the PID to 0 (kernel PID) which
is usually the case during a normal kernel boot. This would fix the kexec

Now that we have relocatable kernel, supporting CRASH_DUMP only requires
turning the switches on for UP machines.
We don't have kexec support on 47x yet. Enabling SMP support would be done
as part of enabling the PPC_47x support.

UPDATE: Minor update in Copyright assignment in misc_32.S
Added requirement of upstream kexec-tools.
Changes from v1: Uses a tmp mapping in the other address space to setup
the 1:1 mapping (suggested by Sebastian Andrzej Siewior).
Note 1: Should we do the same for kernel
Changes from V1: Uses a tmp mapping in the other address space to setup

Note: Should we do the same for kernel entry code for PPC44x ?
This patch adds kexec support for PPC440 based chipsets.This work is based
on the
address overflow in TP allocation.
Changes from V1: Fixed the addr calculation for uImage support.

PPC32 ELF ABI expects r2 to be loaded with Thread Pointer, which is 0x7000
bytes past the end of TCB. Though the purgatory is single threaded, it uses
TCB scratch space in vsnprintf(). This patch allocates a 1024byte TCB
and populates the TP with the address accordingly.
