When I load the zImage directly with xilinx xmd debugger, the kernel start without problem (if I don't have KGDB or SERIAL_TEXT_DEBUG option in my kernel config). But when I try to load the uImage with u-boot, the kernel start but crach befor I can see something on output. The kernel start because I debug it and the platform_init is ok, setup_arch too and it crach after ppc4xx_setup_arch at printk(KERN_INFO "Xilinx ML403 Reference System (Virtex-4 FX)\n") line when the kernel access in printk.c.

I use the opb_uart16550 IP in my Xilinx design and the associat drivers in u-boot and linux.

What are you passing for the kernel command line? Can you post your .config?
