* ice40: Add support for SB_GB_IOSylvain Munaut2018-11-191-0/+1
| | | | | | | | | | 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>
* ice40: Introduce the concept of forPadIn SB_GBSylvain Munaut2018-11-191-0/+2
| | | | | | | | | | | | | | Those are cells that are created mainly to handle the various sources a global network can be driven from other than a user net. When the flag is set, this means the global network usually driven by this BEL is in fact driven by something else and so that SB_GB BEL and matching global network can't be used. This is also what gets used to set the extra bits during bitstream generation. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
