From 8092e9d0e0c6f279e27bad5cf3ee7daf7e22f54b Mon Sep 17 00:00:00 2001 From: Camelia Groza Date: Tue, 13 Apr 2021 19:47:57 +0300 Subject: [PATCH] board: freescale: t208xrdb: fdt fixups under DM_ETH Disable the FMan mEMAC 5 and 6 nodes from the fdt since they are not available under the supported RCW. Also disable the associated "fsl,dpa-ethernet" nodes that reference them. This is a simplified version of the fdt_fixup_fman_ethernet call for use under DM_ETH.
