* ice40: Add support for SB_GB_IOSylvain Munaut2018-11-191-0/+3
| | | | | | | | | | During packing we replace them by standard SB_IO cells and create the 'fake' SB_GB that matches that IO site global buffer connection. It's done in a separate pass because we need to make sure the nextpnr iob have been dealt first so we have our final Bel location on the SB_IO. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
