ca7858bb88 Port of RTEMS to the Texas Instruments C3x/C4x DSP families including 
a BSP (c4xsim) supporting the simulator included with gdb.  This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.

An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU.  This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.

cf1f72ea33 Moved i386 and m68k cache management code to libcpu. Everything 
now is an implementation of the prototypes in rtems/rtems/cache.h.
The libcpu/i386/wrapup directory is no longer needed.
The PowerPC needs this done to it.

8ef38186fa Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine Gauthier 
<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

458bd343e2 This is another pass at making sure that nothing outside the BSP 
unnecessarily uses any variables defined by the BSP.  On this
sweep, use of BSP_Configuration and Cpu_table was eliminated.

A significant part of this modification was the addition of
macros to access fields in the RTEMS configuration structures.

This is necessary to strengthen the division between the BSP independent
parts of RTEMS and the BSPs themselves.  This started after
comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.

6fc973e39b Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: 
Here is another fix, which addresses a few more or less severe bugs in
    configuration and unix/posix:

    * Configuration fix: c/src/lib/configure.in didn't handle RDBG correctly

    * Configuration fix: make depend was non-functional in
      c/src/lib/libc/Makefile.in
    * Configuration fix: stray comment removed from aclocal/target.m4

    * RTEMS fix: termios support for unix/posix now uses the host's headers
      only (was completely broken).
    - Don't install RTEMS's newlib sys/termios.h for unix (sys/termios.h
      apparently is a newlib specific header)
    - To be able to compile RTEMS's  termios.c with glibc2.1, glibc-2.1
      needs __USE_MISC, which is a private define from gcc's features.h, being
      defined only when _BSD_SOURCE of _SVID_SOURCE is defined.  RTEMS's
      termios apparently implements BSD, thus -D_BSD_SOURCE was added to
      Linux-posix.cfg.
    - Conflicting definitions for  __USE_MISC and _BSD_SOURCE inside of
      RTEMS codes removed due to definition of _BSD_SOURCE on the toplevel.

    This fix has been tested with linux/posix (primary glibc2.1 native),
    linux/posix (secondary libc5 native), sh/gensh1, i386/pc386 and a couple
    of other bsp's/CPU.

    To apply:

        cd <srcdir>
        patch -p1 < rtems-rc-19990709-9.diff

    and
        aclocal -I aclocal && automake && autoconf
        cd c/src/lib; autoconf

    or
        ./autogen

07a3253de2 Added base version of file system infrastructure. This includes a major 
overhaul of the RTEMS system call interface.  This base file system is
the "In-Memory File System" aka IMFS.

The design and implementation was done by the following people:

  + Joel Sherrill (joel@OARcorp.com)
  + Jennifer Averett (jennifer@OARcorp.com)
  + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com)
  + Kerwin Wade (wade@OARcorp.com)

PROBLEMS
========
  + It is VERY likely that merging this will break the UNIX port.  This
    can/will be fixed.

  + There is likely some reentrancy/mutual exclusion needed.

  + Eventually, there should be a "mini-IMFS" description table to
    eliminate links, symlinks, etc to save memory.  All you need to
    have "classic RTEMS" functionality is technically directories
    and device IO.  All the rest could be left out to save memory.

388be68fbc Patch from Ian Lance Taylor <ian@airs.com>: 
The reentrant versions of the malloc functions in
        c/src/lib/libc/malloc.c
    do not match the definitions in newlib.  These will be used if you use
    newlib routines such as fdopen.  I believe this patch to malloc.c is
    needed to provide the correct versions.

e8512eb679 incorporate Tony's patches: 
+ c/src/lib/libc/support/generic/malloc.c did not initialize the
    sbrk amount
  + _Thread_Handler in c/src/exec/rtems/thread.c left a window
    during the begin extension which could result in a context switch

fixed places which did not correctly distinguish between an
CPU_isr and a CPU_isr_entry.
