* | More adjustments to .bba file locationsLarry Doolittle2020-01-141-1/+1
|/ | | | | | | | | | Follows PM discussion with Marcus Comstedt. Extend changes in .bba file location (made in commit b6a7b60) to ice40 and MSVC cases, so all cases become compatible with read-only access to git tree. Only known down-side is inefficiency when building out-of-tree for multiple architectures; people following that use case should consider using PREGENERATED_BBA_PATH. It would be nice if there were less copy-paste in MSVC vs. non-MSVC content in family.cmake, but that would have to be addressed by someone more skilled in Cmake and MSVC.
* Remove barrier to out-of-tree buildsLarry Doolittle2020-01-121-2/+1
| | | | | With this change, nextpnr can build successfully (and run correctly) using the git tree as a read-only reference. No change in behavior observed for in-tree builds.
