Alexander Graf ded57c5f3a device tree: give dt more size
We currently load a device tree blob and then just take its size x2 to
account for modifications we do inside. While this is nice and great,
it fails when we have a small device tree as blob and lots of nodes added
in machine init code.

So for now, just make it 20k bigger than it was before. We maybe want to
be more clever about this later.

Alexander Graf ccbcfedd17 device tree: dont fail operations
When we screw up and issue an FDT command that doesn't work, we really need to
know immediately and usually can't continue to create the machine. To make sure
we don't need to add error checking in all device tree modification code users,
we can just add the fail checks to the qemu abstract functions.

Alexander Graf 80ad781643 device tree: add add_subnode command
We want to be able to create subnodes in our device tree, so export it through
the qemu device tree abstraction framework.

Alexander Graf d69a8e6387 device tree: add nop_node
We have a qemu internal abstraction layer on FDT. While I'm not fully convinced
we need it at all, it's missing the nop_node functionality that we now need
on e500. So let's add it and think about the general future of that API later.

David Gibson c489749030 Allow qemu_devtree_setprop() to take arbitrary values
Currently qemu_devtree_setprop() expects the new property value to be
given as a uint32_t *.  While property values consisting of u32s are
common, in general they can have any bytestring value.

Therefore, this patch alters the function to take a void * instead,
allowing callers to easily give anything as the property value.

aurel32 f652e6af11 Implement device tree support needed for Bamboo emulation
To implement the -kernel, -initrd, and -append options, 4xx board emulation
must load the guest kernel as if firmware had loaded it. Where u-boot would be
the firmware, we must load the flat device tree into memory and set key fields
such as /chosen/bootargs.

This patch introduces a dependency on libfdt for flat device tree support.
