Hi ,
we were able to get the u-boot up on MPC8272ADS board . We are just
struck up in bringing up the Linux... we get the following errors ..
actually we made a uImage from vmlinux and tried to tftp and used bootm
100000 , we eneded up with these errors ...actually after the message
Uncompressing Kernel Image ... OK board gets reset .Any help would be
thankfull.

I can suggest to try the current 2.6, on which 8272 is supported and known to work. A problem with binary you got is possibly because of configuration incompatibility of your u-boot and kernel binary.
