-This is the README file for libcpu.

-This directory contains reusable libraries which are CPU dependent but not
-target board dependent.  For example, the PowerPC has an on CPU decrementer
-register which may be used by all PowerPC BSP's for the Clock and Timer
-Drivers.
-
-Other examples include the caching support for the m68k CPU models and
-MIPS CPU model exception vectoring routines.  This level of support
-will make it easier for others developing embedded applications on a given
-CPU.
