Subject: net: fec_mxc: Add support for i.MX91
X-Git-Tag: v2026.04-rc2~11^2~27
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a79ea5b36e1410ff7f551bcb2cc542185371586;p=thirdparty%2Fu-boot.git

net: fec_mxc: Add support for i.MX91

The i.MX91 SoC reuses the ENET FEC from i.MX93. Add all required driver
checks to make it work also on the i.MX91 based platforms.
