BSP and Device Driver Development Guide
This class of code provides a reusable library of peripheral device drivers which can be tailored easily to a particular board. The libchip library is a collection of reusable software objects that correspond to standard controllers. Just as the hardware engineer chooses a standard controller when designing a board, the goal of this library is to let the software engineer do the same thing.
The source code for the reusable peripheral driver library may be found
in the directory c/src/lib/libchip. The source code is further
divided based upon the class of hardware. Example classes include serial
communications controllers, real-time clocks, non-volatile memory, and
network controllers.
