Also, you need a recent version of U-Boot (for  example  99c2fdab  or
later).
I'm using U-Boot 1.2.0-gbc2b9c33-dirty (Feb 22 2007 - 09:53:14). Is that 
recent enough? (I don't know exactly what you mean with "99c2fdab", is 
this the second number after "1.2.0-"?)
No, that is *way* too old.

The number after the "-g" is the (initial 8 digits of the) git commit
ID. You can use this to identify  a  spoecific  version  in  the  git
repository.
Maybe the problem is the missing tqm5200.dtb file. I have booted the 
kernel without it (just bootm 200000). Does the kernel need this file? I 
Yes. An arch/powerpc kernel will not run without a proper device tree.
found a tqm5200.dts file the the kernel sources, but the device tree 
compiler (dtc) seems not to be in the 4.1 ELDK. Do I have to install 
this compiler and build the appropriate dtb file?
Yes, this is correct. dtc will be included with ELDK 4.2.
In older kernels it was O.K. just to uncheck the SM501 drivers in the 
kernel configuration. Has this changed?
As mentioned above, with arch/powerpc you always need a  device  tree
blob.

Best regards,

Thanks, Wolfang, now it's booting fine!
I've updated u-boot to the newest git version, builded the device tree 
file and now everything's working.

Hello Oliver,

My problems continue, could you summarize your steps to bring up the board?
which u-boot version is used?
how build tqm5200.dts file?
did you test pci bus?

Thanks.
