From 0e2afc8368b632ffb195d588ec2315ffbbf0a7e9 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 11 Apr 2020 21:18:59 +0200 Subject: fdtdec: Add weak function to patch U-Boot DT right after fdtdec_setup() Add weak function which is called right after fdtdec_setup() configured the U-Boot DT. This permits board-specific adjustments to the U-Boot DT before U-Boot starts parsing the DT. This could be used e.g. to patch in various custom nodes or merge in DT fragments from prior-stage firmware.
