My apologies, this is misleading/incorrect. Rebooting from Linux,
reset command in u-boot and even pushing the reset button on the
development board all lead to this condition (address 0xfed0c560 with
value of 0x2003cc80). On first boot, address 0xfed0c560 has a value of
0x2003cc81 (SERIRQ function selected).

I'll update the commit message, add your reviewed-by and post a v2.
