With the RTOS mainline gaining some support for code in HyperRAM, it would be nice to be able to load such images in over OpenOCD without needing to write code to do bounce buffering.

While here, also give the debug host access to the system_info peripheral, to provide some more diagnostic information.

Should resolve #381, I think?

Thanks! Using the openFPGALoader flow with that bitstream, I am then able to load both Hello World and the RTOS test suite over OpenOCD.
