tests: Create base classes to encapsulate common test configurations Most of the test cases currently contain a large amount of duplicated boiler plate code. This changeset introduces a set of classes that encapsulates most of the functionality when setting up a test configuration. The following base classes are introduced: * BaseSystem - Basic system configuration that can be used for both SE and FS simulation. * BaseFSSystem - Basic FS configuration uni-processor and multi-processor configurations. * BaseFSSystemUniprocessor - Basic FS configuration for uni-processor configurations. This is provided as a way to make existing test cases backwards compatible. Architecture specific implementations are provided for ARM, Alpha, and X86.

config: Make configs/common a Python package Continue along the same line as the recent patch that made the Ruby-related config scripts Python packages and make also the configs/common directory a package. All affected config scripts are updated (hopefully). Note that this change makes it apparent that the current organisation and naming of the config directory and its subdirectories is rather chaotic. We mix scripts that are directly invoked with scripts that merely contain convenience functions. While it is not addressed in this patch we should follow up with a re-organisation of the config structure, and renaming of some of the packages.

config: Move the memory instantiation outside FSConfig This patch moves the instantiation of the memory controller outside FSConfig and instead relies on the mem_ranges to pass the information to the caller (e.g. fs.py or one of the regression scripts). The main motivation for this change is to expose the structural composition of the memory system and allow more tuning and configuration without adding a large number of options to the makeSystem functions. The patch updates the relevant example scripts to maintain the current functionality. As the order that ports are connected to the memory bus changes (in certain regresisons), some bus stats are shuffled around. For example, what used to be layer 0 is now layer 1. Going forward, options will be added to support the addition of multi-channel memory controllers.

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 Change-Id: Ibd7f763b7248835c624309143cb9fc29d56a69d1 Reviewed-by: Radhika Jagtap <radhika.jagtap@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>
