Originally Gitea issue #2 by @jk-ozlabs on 2022-10-14
The FSI mux signal from the Sequoia connector, pin E4, is connected to pin B51 of the DC-SCI connector.
However, B51 is a USB2_DN signal, so isn't suitable as the FSI mux input
It would probably make more sense to move this to one of the I3C pins, like the FSI clk/dat lines.
On the Artix DC-SCM implementation, this is connected to a separate USB device, and not the FPGA, so we can't work-around this in gateware.
