BSP and Device Driver Development Guide
This class of code includes the foundation
routines for the executive proper such as the context switch and
the interrupt subroutine implementations. Sources for the supported
processor families can be found in c/src/exec/score/cpu.
A good starting point for a new family of processors is the
no_cpu directory, which holds both prototypes and
descriptions of each needed CPU dependent function.
CPU dependent code is further subcategorized if the implementation is dependent on a particular CPU model. For example, the MC68000 and MC68020 processors are both members of the m68k CPU family but there are significant differents between these CPU models which RTEMS must take into account.
