 * Due to silicon errata, routing via MSS IOs doesn't work on ES devices.
 * Instead, i2c1, appearing on B1/C1, which are normally MSS IOs, is routed
 * via the fabric and back to B1/C1 via "fabric-test" functionality.
 * This is done silently by Libero, so the iomux0 setting for i2c1 has to
 * be fabric IO, despite tooling etc saying that MSS IOs are used.
 *
 * See Section 3.3 of https://ww1.microchip.com/downloads/aemDocuments/documents/FPGA/ProductDocuments/Errata/polarfiresoc/microsemi_polarfire_soc_fpga_egineering_samples_errata_er0219_v1.pdf
