4 Subject: [PATCH 29/31] tools: mtk_image: split the code of generating NAND
5 header into a new file
6
7 The predefined NAND headers take too much spaces in the mtk_image.c.
8 Moving them into a new file can significantly improve the readability of
9 both mtk_image.c and the new mtk_nand_headers.c.
10
11 This is a preparation for adding more NAND headers.
