Very first test to read something from SD Card :)

SD Card init succeeded, open file also. The code does not really load yet anything from SD Card, but the ability to access files from SD is at least proven now.

Propeller V 1.0 verilog code (unoptimized version), results with Vivado 2014.4 standard settings

A bit more than 50% of LUTs are consumed. It is possible to optimize the prop HDL code to use DSP48, this would save a few LUTS. Fitting 2 Propeller cores may be possible, or one with more COG.
