+ \begin{itemize}
+   \item Pinmux: multiplexer of functions onto pins\\
+            {\it DRAM Cell != DDR3/4, Mux Cell != Muxer}
+   \item Strategically extremely important to Commercial SoC success\\
+            STMicro, Rockchip, Freescale, Samsung, {\bf EVERYONE}
+   \item Bizarrely, a libre-licensed multi-way Pinmux doesn't exist.\\
+         {\it not on anyone's radar. at all.}
+         SiFive IOF not enough.
+   \item Verification (scenario analysis) and auto-generation of
+                TRM, header files, device-tree files, pretty much everything
+                makes sense (to any "lazy" Software Engineer...)
+   \item Corporations with their own pinmux unlikely to be interested.
+   \item http://git.libre-riscv.org/?p=pinmux.git \\
