Device trees are an attempt to move that information out of the code and into a separate data structure.
More to the point, device trees are a standard way for the boot code to communicate platform configuration to the kernel. For example, the kernel needs to be told how much RAM exists. The device tree replaces a hodgepodge of ad hoc "boot records," "BIOS information structures," and hyper-extensions of the kernel cmdline.
