From b6bb61fd3818f4a3025fedbe4d15dbeeaef6ee82 Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Tue, 2 Aug 2022 17:21:34 +0800 Subject: [PATCH 28/31] tools: mtk_image: split gfh header verification into a new function The verification code of gfh header for NAND and non-NAND are identical. It's better to define a individual function to reduce redundancy.
