Question one: Why the device tree is needed. In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation Demand. But too many platforms and different hardware have led to more and more such code, such as Arch/arm/plat-xxx and arch/arm/mach
