Wendy Elsasser ca0fd665dc mem: Update DRAM configuration names

Names of DRAM configurations were updated to reflect both
the channel and device data width.

Previous naming format was:
	<DEVICE_TYPE>_<DATA_RATE>_<CHANNEL_WIDTH>

The following nomenclature is now used:
	<DEVICE_TYPE>_<DATA_RATE>_<n>x<w>
where n = The number of devices per rank on the channel
      x = Device width

Total channel width can be calculated by n*w

Example:
A 64-bit DDR4, 2400 channel consisting of 4-bit devices:
	n = 16
	w = 4
The resulting configuration name is:
	DDR4_2400_16x4

Updated scripts to match new naming convention.

Added unique configurations for DDR4 for:
1) 16x4
2) 8x8
3) 4x16

Learning_gem README
-------------------
This directory contains the configuration scripts used in the "Learning gem5"
book. The scripts contained in these directories are for educational purposes
only and should not be used for architectural research as-is.

"Learning gem5" is currently in early development stages. A pre-alpha working
version of the book can be found at the following URL.

http://lowepower.com/jason/learning_gem5/

This directory is broken into one subdirectory per part of the book.

Goals of these scripts
~~~~~~~~~~~~~~~~~~~~~~
These scripts are not necessarily useful outside the scope of the learning
gem5 book. The goal is to include the learning gem5 scripts, following the
book as closely as possible, so that the regression tester will catch any
changes that affect the book.

For general users, these are *not* good scripts to use for running complex
architectural experiments. These scripts *are* a good starting point example
of how to write your own scripts for experiments.
