From 5988af2319781bc8e0ce418affec4e09cfa77907 Mon Sep 17 00:00:00 2001 From: Rohit Hagargundgi Date: Tue, 12 May 2009 13:46:57 -0700 Subject: mtd: Flex-OneNAND support Add support for Samsung Flex-OneNAND devices. Flex-OneNAND combines SLC and MLC technologies into a single device. SLC area provides increased reliability and speed, suitable for storing code such as bootloader, kernel and root file system. MLC area provides high density and is suitable for storing user data. SLC and MLC regions can be configured through kernel parameter.
