routines and structures that require CPU model specific information
are now in libcpu. This required significant rework of the
score/cpu header files and the creation of multiple header files
and subdirectories in libcpu/i960.

that decouples exec/ for the sh, m68k and i960 from targopts.h.
NOTE: The change to system.h is a hack to enable cpuopts.h
for some targets, but keep using targopts.h for others - I know it
does *not* work for sparc, mips, i386 and ppc. This will have
to be addressed as work continues on multilibing.

that addresses aspects of the targopts.h multilib related
issues.
Changes:
* Move targopts.h to libbsp/include, because the current targopts.h
actually is a per-BSP-header and therefore can not stay below exec/.
* Introduce an autoheader generated header file
(exec/score/include/rtems/score/cpuopts.h), which shall take per-cpu
configuration options only.
* Move all autoconf-detectable/configure specified per-cpu
option-defines from targopts.h to cpuopts.h.
* Add Makefiles to the libbsp/shared directory hierarchy.
Notes:
* The new per-bsp targopts.h in libbsp includes the per-cpu
cpuopts.h. This way, the new targopts.h is kept backward compatible
to the old targopts.h and existing BSPs which (carelessly) include
targopts.h (i386, ppc) should be kept working when using the
multilib-disabled configuration scheme.
* cpuopts.h is not yet complete, because the per-BSP make-targopts
rules from custom/<BSP>.cfg files can not be applied to files below
exec/ when building multilibs.
* All files below exec/ should not include targopts.h anymore, but
should include cpuopts.h instead. However, eliminating inclusion of
targopts.h currently triggers further structural / header file inclusion
related issues, because several ports apply BSP or CPU_MODEL specific
defines from targopts.h below exec/

from score/cpu to libcpu because the determination of which to use is
based on RTEMS_CPU_MODEL. Thus it can not be determined based solely on
multilib information.

<corsepiu@faw.uni-ulm.de> to fix the following:
* lib/configure.in actually is libc's configure.in, so let it depend
on libc not on lib [In my Cygnus/GNU configuration scheme, lib/include
and lib/libc are treated as one unit, while libcpu and libbsp are
treated as separate units.]
* Allow empty --enable-bare* flags for the bare bsp. The formerly
used scheme is too strict for our multilib experiments.

<corsepiu@faw.uni-ulm.de> that migrates the SH port to
multilib'ing. This patch involved moving a number of
files in the CVS repository, adding new files, and
deleting files from their previous location. Ralf
gave good instructions (not repeated here) and here
are his notes:
Note 1: In this version, I did not change the installation points of
the headers which are moved inside of the source-tree. This is a
temporary hack for not breaking compatibility with 4.5 based BSPs,
but will probably not last once having real multilibs (We would have
include file conflicts when several BSPs/CPU_MODELS share a common
installation prefix).
Note 2: I hope not to have broken too much, but I would not be
astonished if something goes wrong.
Note 3: There are more patches to come :)

<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860.
