boot cuImage on an old u-boot

[Sebastian Siewior]

I have here a mpc8540ads board and a u-boot 1.0.0. I've build the
defconfig for the board and I tried to boot the genarated
cuImage.mpc8540ads image. After the bootm command I see just

|8540> bootm 1000000
|## Booting image at 01000000 ...
|   Image Name:   Linux-2.6.26
|   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
|   Data Size:    1232711 Bytes =  1.2 MB
|   Load Address: 00400000
|   Entry Point:  004005ac
|   Verifying Checksum ... OK
|   Uncompressing Kernel Image ... OK
|

I don't see the device tree fixups printfs, so crash happend quite
early. Anyone an idea what I could have done wrong?
