Sebastian Huber a8865f8b41 score: Introduce CPU_CACHE_LINE_BYTES
Add CPU_CACHE_LINE_BYTES for the maximum cache line size in bytes.  The
actual processor may use no cache or a smaller cache line size.

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.
