In the world of embedded systems, Single Board Computers (SBCs), and Android devices, booting an operating system is not as straightforward as it is on a standard desktop PC. Standard PCs rely on a unified BIOS or UEFI interface to discover hardware automatically. Embedded hardware architectures, particularly ARM, RISC-V, and MIPS, require a different approach. dtb firmware

The data flowed as a torrent of structure: nodes, properties, phandles. /soc/spi@f2000000 compatible = "vendor,spi-controller"; reg = <0xf2000000 0x1000>; interrupts = <0 42 4>; status = "okay"; ; dtc -I dts -O dtb -o my-board

Historically, the Linux kernel contained hard-coded details for every piece of hardware it supported. As the number of ARM-based devices exploded, the kernel became cluttered with "platform code." To solve this, developers moved hardware descriptions out of the kernel and into a separate data structure called a Device Tree.
