From c93ff6bf16523d33e991a1fadde1b8d63eb7cd2c Mon Sep 17 00:00:00 2001 From: Roman Tereshonkov Date: Thu, 17 Feb 2011 13:44:42 +0200 Subject: [PATCH] mtd: omap: add new variable to platform data to control onenand unlocking New variable skip_initial_unlocking is added to the omap_onenand_platform_data. This is used to inform the onenand driver to skip onenand unlocking when it is initialized.
