From 00d10eb0410d2459727307d5eea562247959db2f Mon Sep 17 00:00:00 2001 From: Macpaul Lin Date: Fri, 15 Apr 2011 21:37:11 +0000 Subject: ftsmc020: move ftsmc020 static mem controller to driver/mtd Move the header file and definitions of ftsmc020 static memory control unit from a320 SoC folder to "drivers/mtd" folder. This change will let other SoC which also use ftsmc020 could share the same header file.
