From 310995d9f91ae56082b49be06fe8c3d01424f8f6 Mon Sep 17 00:00:00 2001 From: Wilson Lee Date: Wed, 15 Nov 2017 01:14:35 -0800 Subject: [PATCH] mtd: zynq: nand: Move board_nand_init() function to board.c Putting board_nand_init() function inside NAND driver was not appropriate due to it doesn't allow board vendor to customise their NAND initialization code such as adding NAND lock/unlock code. This commit was to move the board_nand_init() function from NAND driver to board.c file. This allow customization of board_nand_init() function.
