From a00e0f7ae5a3058dc8dd520d1d449d4c8806e5f8 Mon Sep 17 00:00:00 2001 From: Stanislav Pinchuk Date: Wed, 20 Jan 2021 21:52:23 +0300 Subject: [PATCH] do not pass NULL pointer to libfdt Re-send because of line-wraps. Without this patch, u-boot just hangs if the fdt pointer is not initialized. The diagnostic subsystems are not yet initialized, so all you get is a blind hang.
