From 20ebf03eab571b25e9f62b2764ab84932111dcd6 Mon Sep 17 00:00:00 2001
From: Weijie Gao <weijie.gao@mediatek.com>

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.
