| | | | | | | | | | | | | | The definitions for uint32_t, uint64_t report as undefined when compiling under GCC13. They were previously found by transitive includes, but this is not guaranteed to work, and GCC13 forced the issue.

| * | ice40: Support for undriven / unconnected output portsSylvain Munaut2023-01-291-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | If a port specified as output (and thus had a $nextpnr_obuf inserted) is undriven (const `z` or const `x`), we make sure to not enable the output driver. Also enable pull-ups if it was requested by the user. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
| * | ice40: Rework pull-up attribute copy to SB_IO blocksSylvain Munaut2023-01-291-8/+14
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | We try to copy the attribute only when there is a chance for the output driver to not be active. Note that this can _also_ happen when a port is specified as output but has a TBUF, which the previous code wasn't handling. We could copy the attribute "all-the-time" but this would mean if a user specified a `-pullup yes` in the PCF for a permanently driven output pin, we'd be burning power for nothing.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This chip is used in the Tangnano9k board. * all parameters of the rPLL primitive are supported; * all PLL outputs are treated as clock sources and optimized routing is applied to them; * primitive rPLL on different chips has a completely different structure: for example in GW1N-1 it takes two cells, and in GW1NR-9C as many as four, despite this unification was carried out and different chips are processed by the same functions, but this led to the fact that you can not use the PLL chip GW1N-1 with the old apicula bases - will issue a warning and refuse to encode primitive. In other cases compatibility is supported. * Cosmetic change: the usage report shows the rPLL names without any service bels. * I use ctx->idf() on occasion, it's not a total redesign.

|/ | | | | | | | | | Eigen considers the EIGEN3_INCLUDE_DIRS and EIGEN3_DEFINITIONS variables to be deprecated and they will no longer be exported in the next release after 3.4.0: https://gitlab.com/libeigen/eigen/-/commit/f2984cd0778dd0a1d7e74216d826eaff2bc6bfab Use the IMPORTED target instead, which seems to be the preferred way of consuming third-party CMake libraries.
