From 68b960e299f7a31c986d6e5c6244a31f3dd4b8fd Mon Sep 17 00:00:00 2001 From: Herve Codina Date: Tue, 10 Feb 2026 18:33:30 +0100 Subject: [PATCH] fdtdump: Remove dtb version check fdtdump checks the dtb version and simply failed if the dtb version is newer than the last version supported by fdtdump. This check is not needed and too restrictive. Indeed, fdtdump does read-only operations on the dtb provided and should rely only the last_comp_version header field to know whether or not it can read the dtb. The current check also avoid the use of fdtdump in tests checking for the libfdt behavior when an new (future) dtb version is used. Relax fdtdump checks removing the check of the dtb version header field.
