| * intel: Map M9K BRAM only on families that have itDan Ravensloft2019-07-234-5/+12
| | | | | | | | | | | | | | | | This regresses Cyclone V and Cyclone 10 substantially, but these numbers were artificial, targeting a BRAM that they did not contain. Amusingly, synth_intel still does better when synthesizing PicoSoC than Quartus when neither are inferring block RAM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cyclonev has been a "supported" family since the initial commit. The old commit message suggested to use a10gx which is incorrect. Aside from the obvious lack of functional change due to this just being a help message, users who were previously using "a10gx" for "cyclonev" will also have no functional change by using "cyclonev" instead.

| | | | | | | | | | | | | | | | | | | | | | | | The help and code default to MAX10 for the family, however the couple of if ladders defaulted to cycloneive. Fix this inconsistency and the next patch will clean it up. Signed-off-by: Ben Widawsky <ben@bwidawsk.net>
