Arm device tree and linux device drivers
Arm device tree and linux device driversHoucheng LinThis document discusses how the Linux kernel supports different ARM boards using a common source code base. It describes how device tree is used to describe hardware in a board-agnostic way. The kernel initializes machine-specific code via the device tree and initializes drivers by matching compatible strings. This allows a single kernel binary to support multiple boards by abstracting low-level hardware details into the device tree rather than the kernel source. The document also contrasts the ARM approach to the x86 approach, where BIOS abstraction and standardized buses allow one kernel to support most x86 hardware.
