[U-Boot-Users] [PATCH 1/3] ppc: Report back the location we put the device tree if we dont boot

[Kumar Gala]

Its useful to know where the device tree is if we have set 'autostart'
to 'no.  We come back to the prompt after a boot command and we can
than post process the device tree but we need to know where it was put
report this back via the env variable 'bootm_fdtaddr'.
