I take that back. Patch 4 causes a problem, at least when applied on top of u-boot/master from today. Basic serial output works just fine, and I can interact with U-Boot without issue. However, when the boot scripts execute and load an extlinux.conf, U-Boot hangs. Up to patch 3, everything is fine.
