The SMP release mechanism for FSL book3e is different from when booting
with normal hardware. In theory we could simulate the normal spin
table mechanism, but not at the addresses U-Boot put in the device tree
-- so there'd need to be even more communication between the kernel and
kexec to set that up. Instead, kexec-tools will set a boolean property
linux,booted-from-kexec in the /chosen node.

Add a global binding for the chosen node. Include a description of the
stdout-path, and an explicit statement on its extra options in the
context of a UART console.
