From 8dbfae1ef04311ba19d6b6c9a4d8fdddbb90ab0f Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 4 Mar 2013 15:39:18 +0200 Subject: [PATCH] mtd: nand_ids: introduce helper macros Introduce helper macros for defining NAND chips. These macros do not really add much value in the current code-base. However, we are going to add full ID support which adds some more complexity to the table, and helper macros become useful for readability.
