Hi,
I have been working with using XEN on ODROID-XU4 board.I would like to
optimize the boot time of XEN to 3s. Currently it is taking about 5s to
boot.I have disabled the prints.There is about 4s delay before kernel load.
Below is the log before disabling prints.

I'm getting a delay after Freed 264kB init memory.I'm not able to figure
out the reason for delay.Is there any way to reduce the delay?Please help
me to solve this.
Thank you.
