Subject: boards: avoid duplicating platforms that can be found in migen/litex-buildenv
X-Git-Tag: 24jan2021_ls180~1418
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=68e1dfca2880ebcbbd899116c824bcd8471e34a4;p=litex.git

boards: avoid duplicating platforms that can be found in migen/litex-buildenv

The platforms that are kept are the ones used for litex development.
