2011-10-06device tree: give dt more sizeAlexander Graf
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. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-10-06device tree: dont fail operationsAlexander Graf
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.

2011-10-06device tree: add add_subnode commandAlexander Graf
We want to be able to create subnodes in our device tree, so export it through the qemu device tree abstraction framework. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-10-06device tree: add nop_nodeAlexander Graf
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. Signed-off-by: Alexander Graf <agraf@suse.de>

2011-04-01Allow qemu_devtree_setprop() to take arbitrary valuesDavid Gibson
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.

2008-12-16Implement device tree support needed for Bamboo emulationaurel32
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.
