* | ice40: cmake: fix build with pregenerated bba pathSean Cross2019-10-241-8/+0
|/ | | | | | | | | | | | | | | When building using non-pregenerated bba files, the rule to create bbasm files gets called twice: once unconditionally, and once as part of the conditional that determines we're not using a pregenerated bba path. If we _are_ using a pregenerated bba path, then this rule gets called anyway, resulting in a build error. Remove the duplicate, unconditional creation of the bba file generation, to fix the build when using pregenerated files, and to speed up the build when not using pregenerated files.
