From cadb1a858d071e4ec6afdacc9ad5c7057cae699d Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Fri, 9 Sep 2022 20:00:21 +0800 Subject: tools: mtk_image: split the code of generating NAND header into a new file The predefined NAND headers take too much spaces in the mtk_image.c. Moving them into a new file can significantly improve the readability of both mtk_image.c and the new mtk_nand_headers.c. This is a preparation for adding more NAND headers.
