From 3d468b6d6052293ad3b8538b8277077981c28286 Mon Sep 17 00:00:00 2001 From: Jason Cooper Date: Mon, 27 Feb 2012 16:07:13 +0000 Subject: ARM: kirkwood: add dreamplug (fdt) support. Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g. Then, switched to SPI based NOR flash. After talking to Arnd Bergman, chose an incremental approach to adding devicetree support. First, we use the dtb to tell us we are on the dreamplug, then we gradually port over drivers. Driver porting will start with the uart (see next patch), and progress from there. Possibly, spi/flash/partitions will be next. When done, board-dt.c will no longer be dreamplug specific, and dt's can be made for the other kirkwood boards.
