You set up the device tree to reflect a core 1 boot, but I don't see
where you told U-Boot to use core 1.  You need to use a command like
"cpu 1 release 0x10000000 - $fdt1addr 0x45504150" instead of "bootm go".

Also make sure that you pass -b1 to dtc.

BTW, your e-mail client appears to be inappropriately adding
capitalization to pasted text.
