From 1969b3cc72d1e056eeb8356eae1228302b481208 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 6 Mar 2023 15:53:54 +0100 Subject: [PATCH] arm64: imx8mm: imx8mn: imx8mp: Drop FEC GPR[1] board workaround The FEC interface mode is now configured in common board_interface_eth_init() and called by FEC MAC driver when appropriate. Drop the board side duplicates if the same functionality.
