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.

2617b3450b Restructured so all times are placed in variables and printed in batch
mode at the end of the test.  This eliminates the possibility of IO
blocking a task unexpectedly and messing up the test.

e6424462c3 As part of reducing visibility into rtems and hiding the .inl files
from the application code, this file required more visibility than
is given by default to application code.

3652ad356b Minor bug fixes to get all targets compilable and running. The
single biggest changes were the expansion of the workspace size
macro to include other types of objects and the increase in the
minimum stack size for most CPUs.

3a4ae6c210 The word "RTEMS" almost completely removed from the core.
Configuration Table Template file added and all tests
modified to use this.  All gvar.h and conftbl.h files
removed from test directories.

Configuration parameter maximum_devices added.

Core semaphore and mutex handlers added and RTEMS API Semaphore
Manager updated to reflect this.

Initialization sequence changed to invoke API specific initialization
routines.  Initialization tasks table now owned by RTEMS Tasks Manager.

Added user extension for post-switch.

Utilized user extensions to implement API specific functionality
like signal dispatching.

Added extensions to the System Initialization Thread so that an
API can register a function to be invoked while the system
is being initialized.  These are largely equivalent to the
pre-driver and post-driver hooks.

Added the Modules file oar-go32_p5, modified oar-go32, and modified
the file make/custom/go32.cfg to look at an environment varable which
determines what CPU model is being used.

All BSPs updated to reflect named devices and clock driver's IOCTL
used by the Shared Memory Driver.  Also merged clock isr into
main file and removed ckisr.c where possible.

Updated spsize to reflect new and moved variables.

Makefiles for the executive source and include files updated to show
break down of files into Core, RTEMS API, and Neither.

Header and inline files installed into subdirectory based on whether
logically in the Core or a part of the RTEMS API.

7f6a24abdd Added unused priority ceiling parameter to rtems_semaphore_create.
Rearranged code to created thread handler routines to initialize,
start, restart, and "close/delete" a thread.

Made internal threads their own object class.  This now uses the
thread support routines for starting and initializing a thread.

Insured deleted tasks are freed to the Inactive pool associated with the
correct Information block.

Added an RTEMS API specific data area to the thread control block.

Beginnings of removing the word "rtems" from the core.

3235ad9a2c Support for variable length names added to Object Handler. This supports
both fixed length "raw" names and strings from the API's point of view.

Both inline and macro implementations were tested.

795030965e Added test cases:
+ some from Andy Bray (andy@i-cubed.demon.co.uk) which do not include
    task start up cost.
  + cases for interrupt disable, enable, and flash
