e6890ba1f5 Patch from Eric Norum <eric@cls.usask.ca> to avoid lockup under 
the correct circumstances of DMA buffer size, serial
line interrupts, and ethernet interrupts the termios osend routine would
lock up waiting for the raw output buffer semaphore.

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.

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

7edb9281a2 Following comments from Eric Norum <eric@cls.usask.ca>, a fairly 
substantial upgrade of newlibc.c occurred.  Now the user extension
data area is used rather than notepads and as many routines as possible
were split into other files further reducing the minimum footprint
of an RTEMS executable.

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>.
