[PATCH 10/12] mtd: nand_ids: introduce helper macros

Mon Mar 4 11:42:27 EST 2013
From: Artem Bityutskiy <artem.bityutskiy at linux.intel.com>
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.
