The vmlinux file isn't a bootable kernel image.

If you want a non compressed kernel then try "make Image" and use the 
resulting Image file.  Then you'll have to load it at the appropriate 
location in RAM (usually 0x8000 from the start of physical memory), 
whereas zImage does relocate itself automatically.

Why don't you want to use zImage?  Given that you're using U-Boot you 
should probably use uImage instead anyway (from 'make uImage").
