1: not ppc32 related, noticed while I tried to load dtb/kernel from an ubi
2: the second version of purgatory & dtb support for ppc32.
v1: removed run time change between dreamcast and device tree aware
arch and switched to ifdef
3: libfdt. This library is used for device tree handling and is not
packaged. I'm not sure if upstream wants to support shared libraries
and maintain a stable api. This whole patch has 109KiB and is
available at  I did not want to spam the list.
PPC64 is creating the nodes by hand and they can't replaces nodes.
4: Uses the libfdt to replaces some nodes. Usually the bootloader sets
some properties which are auto enabled like clock speed or MAC
address. This patch allows to take an almost complete device tree and
update the missing nodes from the actual device tree.
