2011-10-06device tree: add add_subnode commandAlexander Graf1-0/+1
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 Graf1-0/+1
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 Gibson1-1/+1
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 emulationaurel321-0/+26
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.
