What is a DTB anyway?
It is a Device Tree Blob. Most desktop Linux machines actively probe for installed hardware to load and initialize various drivers. This can be a slow yet tedious process. To avoid the time required to probe in general, embedded Linux devices use a pre-defined, binary DTB to tell the kernel what is on the board and how to talk to it.
