[ELDK] Sequoia AMCC 440EPx booting using cuImage.sequoia

[Nguyen Phuong Duy]

Hi forks,
I'm trying to booting from u-boot version 1.3.3 without of using dtb file by trying cuImage.sequoia.
These tool i am using:
   linux-2.6.25.7-denx
   uImage version 1.3.3
I have done these steps to build cuImage:
1.make ARCH=powerpc CROSS_COMPILE=powerpc=linux- sequoia_defconfig
2.make ARCH=powerpc CROSS_COMPILE=powerpc=linux- zImage
then I copy the file arch/powerpc/boot/cuImage.sequoia to folder /tftpboot/ on server:
3.cp arch/powerpc/boot/cuImage.sequoia 192.168.1.3:/tftpboot/sequoia
Boot up the board:

Board: Sequoia - AMCC PPC440EPx Evaluation Board, Rev. F, PCI=66 MHz
I2C:   ready
DTT:   1 is 37 C
DRAM:  256 MB

In:    serial
Out:   serial
Err:   serial

Hit any key to stop autoboot:  5                                                                                                                                               0

It just run to that point. I don't know what I am was wrong.
These are enviroment of u-boot 
=> version
U-Boot 1.3.3 (July 19 2008 - 12:58:08)
=> print nfsargs

Please help me.

Thanks and best regards,
