Thanks in advance,
Since you updated u-boot, it might not be setting up the architecture
number properly.
It's also possible that there is an incompatibility between the way
the current u-boot and the kernel pass arguments. With arm
processors, it's "atags".
Do you have the kernel source? Find start.S and you can put debugging
in there; if you can twiddle a GPIO, you can at least look at an LED :)
In u-boot, it's in u-boot/lib_arm/armlinux.c that it starts the
kernel. You'll need to see if your kernel expects tags, and make sure
u-boot passes them.
Which "board" do you have u-boot configured for? I couldn't find this
particular board/cpu in the distribution.
