From 31ff09b7a60bbc80b5df941ec1a12502861b4da9 Mon Sep 17 00:00:00 2001 From: Liang Li Date: Wed, 12 Aug 2009 09:34:29 -0400 Subject: [PATCH] powerpc/83xx: Add localbus node and MTD partitions for SBC834x There is 8MB flash, 8kB EEPROM and 128MB SDRAM on the sbc834x local bus, so add a localbus node in DTS with MTD partitions. The recent U-boot commit fe613cdd4eb moves u-boot to the beginning of flash, hence the legacy label on the partition at the end of flash.
