powerpc/83xx: Add localbus node and MTD partitions for SBC834x
Liang Li [Wed, 12 Aug 2009 13:34:29 +0000 (09:34 -0400)]
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.
