From e2985fc1d684927ce1dd5e5e6d35db8b52302685 Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Fri, 17 May 2013 11:17:30 +0800 Subject: [PATCH] mtd: replace the hardcode with the onfi_feature() The current code uses the hardcode to detect the 16-bit bus width. Use the onfi_feature() to replace it.
