The device tree is a representation of hardware used by the boot loaders (iOS's iBoot and OS X's boot.efi) to provide the kernel with a mapping of hardware. The tree is a hierarchical representation of devices by connection, somewhat similar to Solaris's device tree (/devices), and Linux's /sys/devices.
The device tree can be decrypted by the VFDecrypt keys. A program to dump the IMG3 file format, and in particular the device tree, can be found the companion website to Wiley's OS X and iOS internals book. A dump of the N88 device tree is here.
