You're using the old default-env which does not support uImage on FAT
(only a kernel directly in a partition). Either switch to default-env-2
and mount the FAT ('mount /dev/disk0.0 fat /mnt') before loading the
kernel from /mnt/uImage.
Otherwise for the old default-env take a look at
<1345472428-17417-13-git-send-email-jlu@xxxxxxxxxxxxxx>. Note that for
that to work, the FAT must be mounted by the board code or you need to
setup an automount.
