* ecp5: Proof-of-concept using IdStringList for bel namesD. Shah2021-02-021-4/+3
| | | | | | | | | | | This uses the new IdStringList API to store bel names for the ECP5. Note that other arches and the GUI do not yet build with this proof-of-concept patch. getBelByName still uses the old implementation and could be more efficiently implemented with further development.
