Since 7e5a875fff7d ("Compile libfdt for barebox"), we now also have
libfdt for operating on flattened device trees out of the PBL.
Document this.

 The preferred way of adding board support to barebox is to have devices
 on non-enumerable buses probed from device tree.
-barebox imports the Linux OpenFirmware ``of_*``-API functions for device tree
-parsing, which makes porting the device tree specific bits from device drivers
-very straight forward.
+barebox provide both the Linux OpenFirmware ``of_*`` and the libfdt ``fdt_`` APIs
+for device tree parsing. The former makes porting the device tree specific
+bits from Linux device drivers very straight forward, while the latter can be
+used for very early (PBL) handling of flattened device trees, should this be
+necessary.
 
 Additionally, barebox has support for programmatically fixing up device trees
 it passes to the kernel, either directly via ``of_register_fixup`` or via device
