[U-Boot] cuImage doesn't boot with u-boot 2009.11 version

[narayanasami vijayaraghavan]

Hello uboot experts,
( I am new to board level debugging. So, please excuse if I am asking any
basic question).

Is cuImage format supported with u-boot-2009.11 version?

I am running linux 2.6.32 with powerpc P1020 (freescale) board.  The board
has u-boot version 2009.11.
When I build the uImage and device tree blob separately, it is booting from
u-boot.
But, if I build cuImage format, it doesn't boot, and stops at
"Uncompressing Kernel Image ... OK":

Could you please help? What could have gone wrong here?
