dt: add helper for phandle references
Phandles are the fancy device tree name for "pointer to another node".To create a phandle property, we most likely want to reference to thenode we're pointing to by its path. So create a helper that allowsus to do so....
dt: temporarily disable subtree creation failure check
Usually we want to know when creating a subtree fails. However, whileintroducing this patch set we have to modify the device tree and sometimes have the code to create a subtree in both the binary tree and...
dt: allow add_subnode to create root subnodes
Our subnode creation helper can't handle creation of root subnodes,like "/memory". Fix this by allowing the parent node to be an emptystring, indicating the root node.

device tree: give dt more size
We currently load a device tree blob and then just take its size x2 toaccount 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 addedin machine init code....
device tree: add add_subnode command
We want to be able to create subnodes in our device tree, so export it throughthe qemu device tree abstraction framework.

device tree: dont fail operations
When we screw up and issue an FDT command that doesn't work, we really need toknow immediately and usually can't continue to create the machine. To make surewe don't need to add error checking in all device tree modification code users,...
device tree: add nop_node
We have a qemu internal abstraction layer on FDT. While I'm not fully convincedwe need it at all, it's missing the nop_node functionality that we now needon e500. So let's add it and think about the general future of that API later....

Allow qemu_devtree_setprop() to take arbitrary values
Currently qemu_devtree_setprop() expects the new property value to begiven as a uint32_t *. While property values consisting of u32s arecommon, in general they can have any bytestring value.
Therefore, this patch alters the function to take a void * instead,...

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