Open Firmware Flat Tree and usage.
|
|
----------------------------------
|
|
|
|
As part of the ongoing cleanup of the Linux PPC trees, the preferred
|
|
way to pass bootloader and board setup information is the open
|
|
firmware flat tree.
|
|
|
|
Please take a look at the following email discussion for some
|
|
background.

|
|
The generated tree is part static and part dynamic.
|
|
|
|
There is a static part which is compiled in with DTC and a dynamic
|
|
part which is programmatically appended.
|
|
|
|
You'll need a fairly recent DTC tool, which is available by git at
|
|
|
|
rsync://ozlabs.org/dtc/dtc.git
|
|
|
|
The xxd binary dumper is needed too which I got from
