Hi,
While executing reboot call on my ARMv7 board, the system hangs during
cpu_proc_fin() call.
Commenting out this line of code, the reboot works properly.

ENDPROC(cpu_v7_proc_fin)
is it a CPU_V7 specific issue?
Please provide your valuable input to fix the issue.
Any hint also..will help me in debugging further in this issue.
I have seen above fix in one of the linaro mailing list.

I don't think there is any issue with cpu_v7_proc_fin. In case of the
issue that I was facing, it was fixed by adding a proper reset hook to
my platform.
Please go through following link. I hope that would help.

I'm not totally sure if it's the same issue, but you might want to check
http://lists.arm.linux.org.uk/lurker/message/20120809.031847.ad2088dd.en.html
and the rest of that thread.
Sorry if it's unrelated ;)
Best regards
Dirk
