u-boot porting problem from version 2014 to version 2015

Hi,


I am porting uboot from version 2014-4 to 2015-4 for my custom board.
I made the changes for uart, booting device etc..
Since uboot-2014 version works fine, I have copied the mx6q_4x_mt41j128.cfg file from uboot-2014 version to uboot-2015.
but the booting freezes as shown below:

U-Boot 2015.04-00002-gee628f1769-dirty (May 12 2017 - 14:47:34)

CPU: Freescale i.MX6Q rev1.2 at 792 MHz
CPU: Temperature 23 C
Reset cause: POR
Board: MX6-SabreSD
I2C: ready
DRAM:

I am seeing a lot of code related to ddr in sabresd.c, which was not present in version 2014.

Is there any changes required?

Please help me.

Thanks.

Found the problem, it was some connection issue. 

Now u-boot is booting fine.
