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.
