* oftree: add of_fix_tree()Sascha Hauer2011-12-151-0/+1
| | | | | | | | | | Currently we have of_get_fixed_tree() which assumes that there is a global variable holding a oftree. This seems not very flexible, so for now introduce a of_fix_tree() which takes an fdt_header as argument and walks the list of registered of fixup functions.

* initial oftree command supportSascha Hauer2011-10-191-0/+21
This adds basic device tree command support. So far we can parse a flat device tree (-p), which also stores the tree in memory, dump it (-d) and free (-f) the internally stored tree. The chosen node can be updated with barebox bootargs, no other device tree manipulation is implemented yet. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
