+Subject: [PATCH 55/78] mtd: nand: embed an mtd_info structure into nand_chip
+
+Currently all NAND controller drivers are providing both the mtd_info and
+nand_chip struct and then let the NAND subsystem to initialize a few
+things before registering the mtd instance to the MTD layer.
+Embed an mtd_info field into nand_chip to add some consistency to all NAND
+controller drivers.
+This change will also help factorizing boilerplate code copied in all NAND
+drivers.
