BSP and Device Driver Development Guide
The CPU dependent support files contain routines which aid in the development of applications using that CPU family. For example, the support routines may contain standard trap handlers for alignment or floating point exceptions or device drivers for peripheral controllers found on the CPU itself. This class of code may be found in the following directory:
c/src/lib/libcpu/CPU
CPU model dependent support code is found in the following directory:
c/src/lib/libcpu/CPU/CPU_MODEL
CPU_MODEL may be a specific CPU model name or a name indicating a CPU
core or a set of related CPU models. The file configure.ac in each
c/src/lib/libcpu/CPU directory contains the logic which enables
the appropriate subdirectories for the specific CPU model your BSP has.
