| 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 |
| |
| ftp://ftp.uni-erlangen.de/pub/utilities/etc/xxd-1.10.tar.gz |
