1.  Port the GPIA core to run natively on a TileLink TL-UL interconnect.
1.  Develop the remote-side logic for a [ByteLink interconnect](wiki/ByteLink).  This will let me send read/write requests from the Kestrel-2DX to see if the GPIA is working.  This will serve as a surrogate for the final CPU design that I intend.
1.  Make sure I can toggle LEDs using the debug port interactively from the Kestrel-2DX.
1.  Port my Serial Interface Adapter to the Kestrel-3.
1.  Interactively confirm that the serial link works on the Kestrel-3 in loop-back mode.
1.  Develop final SRAM interface.
1.  Make sure I can perform basic RAM tests interactively from the Kestrel-2DX.
1.  Develop a "ROM" system using block RAMs.  (from CPU's perspective, it's ROM; from the ByteLink interface, it's RAM.)
1.  Make sure I can write to and read back from the "ROM" interactively from the Kestrel-2DX.
1.  Port the KCP53000 to run on the new platform.  Fix perf regressions.  Use TileLink front-side bus.
1.  Write first-boot firmware that writes "Hello world" to the SIA or something.  Upload it from the Kestrel-2DX.
1.  Boot the Kestrel-3 for the first time, and hope for the best.
