[meta-freescale] [IMX6Q Sabre Lite, Linux 3.4.34] Booting is failed in calibrate_delay_converge().

[Shinkyu Kang]

Hi,
My name is Shinkyu, working for Realtimewave in South Korea.
This is first time to write a mail to yocktoproject.org.
I'm testing with IMX6Q SABRE Lite Ev. Board (Boundary Device) Rev. D,
WindRiver Linux 5 which supports to Yockto project and Linux 3.4.34.

When I try to boot with kernel 3.4.34, it loops infinitly at "while(ticks
== jiffies)" in calibrate_delay_converge( ) (Init/calibrate.c)
So, I want to get hints for booting problem from Freescale IMX6Q experts.
