Here are a few patches which are just enough to run the SBI unit tests in a bare metal environment, under U-Boot on boards with a UART needing 32-bit MMIO (which is a rather common configuration in my experience). Though I wonder if we should prefer the SBI debug console extension for puts() output when available.
