Linux boot hang on P1020RDB

Hi,

 

I'm working on P1020RDB and using FSL SDK version 1.4. I've modified machine conf file so that p1020rdb.dts is used instead of p1020rdb-pd_32b.dts as below.

KERNEL_DEVICETREE = "${S}/arch/powerpc/boot/dts/p1020rdb.dts"

 

Now when I try to boot images generated with above change, boot process hangs at Freescale On-Chip EHCI Host Controller as can be seen in below log.

If I rebuild kernel with EHCI disabled, control reaches login prompt.

Any suggestion how can this be resolved?
