Hi Eric,

I have the same board and same problem. It's just an incompatibility between the
DTB and u-boot.
Recent u-boots (and without a doubt also your u-boot 1.3.3) expect aliases
in the DTB, these ones I guess:

.
.
         aliases {
                 ethernet0 = &enet0;
                 ethernet1 = &enet1;
                 serial0 = &serial0;
                 serial1 = &serial1;
                 pci0 = &pci0;
         };
.
.

Not being able to find alias "serial0" (in the DTB) causes this problem.
see u-boot/common/fdt_support.c:fdt_fixup_stdout

Older u-boots don't expect them. My REV A4 board was shipped with
"U-Boot 1.1.6 (Aug 24 2007 - 13:10:12) MPC83XX" (which obviously not expects the aliases).

If I flash a new/custom u-boot (U-Boot 2008.10) the problem occurs.

I assume Freescale ships their REV A4 boards with a u-boot not expecting the
aliases.
I assume your u-boot 1.3.3 is not the one the board was shipped with,
are are you saying it is ?
