+Subject: [PATCH 29/31] 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.
