Geoffrey Blake e826d23a2e Packet: Add derived class FunctionalPacket to enable partial functional reads 
This adds the derived class FunctionalPacket to fix a long standing
deficiency in the Packet class where it was unable to handle finding data to
partially satisfy a functional access.  Made this a derived class as
functional accesses are used only in certain contexts and to not add any
additional overhead to the existing Packet class.

README 

This is the M5 simulator.

For detailed information about building the simulator and getting
started please refer to http://www.m5sim.org.

Specific pages of interest are:
http://www.m5sim.org/wiki/index.php/Compiling_M5
http://www.m5sim.org/wiki/index.php/Running_M5

Short version:

1. If you don't have SCons version 0.98.1 or newer, get it from
http://wwww.scons.org.

2. If you don't have SWIG version 1.3.31 or newer, get it from
http://wwww.swig.org.

3. Make sure you also have gcc version 3.4.6 or newer, Python 2.4 or newer
(the dev version with header files), zlib, and the m4 preprocessor.

4. In this directory, type 'scons build/ALPHA_SE/tests/debug/quick'.  This
will build the debug version of the m5 binary (m5.debug) for the Alpha
syscall emulation target, and run the quick regression tests on it.

If you have questions, please send mail to m5-users@m5sim.org

WHAT'S INCLUDED (AND NOT)
-------------------------

The basic source release includes these subdirectories:
 - m5:
   - configs: simulation configuration scripts
   - ext: less-common external packages needed to build m5
   - src: source code of the m5 simulator
   - system: source for some optional system software for simulated systems
   - tests: regression tests
   - util: useful utility programs and files

To run full-system simulations, you will need compiled system firmware
(console and PALcode for Alpha), kernel binaries and one or more disk images. 
These files for Alpha are collected in a separate archive, m5_system.tar.bz2.
This file can he downloaded separately.

Depending on the ISA used, M5 may support Linux 2.4/2.6, FreeBSD, and the
proprietary Compaq/HP Tru64 version of Unix. We are able to distribute Linux
and FreeBSD bootdisks, but we are unable to distribute bootable disk images of
Tru64 Unix. If you have a Tru64 license and are interested in
obtaining disk images, contact us at m5-users@m5sim.org
