    15 // Overview:
       
    16 // Performs cache checking in order to ensure it is running correctly.
       
    17 // Runs automatically or as manual test. (Type "t_cache help" for details.)
       
    18 // API Information:
       
    19 // class Cache
       
    20 // class L2Cache
       
    21 // Details:
       
    22 // -Test1 - Displays cache properties.
       
    23 // -Test2 - Gets thresholds.
       
    24 // -Test3 - Sets thresholds.
       
    25 // -Test4 - Compares different memory mappings of data.
       
    26 // -Test5 - Compares different memory mappings of code.
       
    27 // -Test6 - Tests Write Back mode.
       
    28 // -Test7 - Tests cache maintenance functions
       
    29 // It can also perform more specified tests if run manually:
       
    30 // - t_cache info				Test1 only
       
    31 // - t_cache data <size_hex>	Runs data chunk test (Test 4) with specified chunk size. For example,
       
    32 // "t_cache data 10000" will run data chunk test against 64KB chunk.
       
    33 // - t_cache code <size_hex>	Runs code chunk test (Test 5) for specified chink size. For example,
       
    34 // "t_cache code 10000" will run code chunk test against 64KB chunk.
       
    35 // - t_cache data+<size_hex>	Runs data chunk test for specified set of chunk sizes. For example,
       
    36 // "t_cache data+1000" will perform data chunk test for sizes 4K, 8K,... up to 512K.
       
    37 // - t_cache code+<size_hex>	Runs code chunk test for specified set of sizes. For example,
       
    38 // "t_cache code+1000" will perform code chunk test for sizes 4K, 8K,... up to 512K.
       
    39 // - t_cache threshold			Diplays thresholds for all caches on the platform.
       
    40 // - t_cache threshold T P C H	Sets new values for cache thresholds:
       
    41 // - "T" specifies the type of cache to whose threshould are to be chenged:
       
    42 // 1  for Instruction (or Unified) Cache.
       
    43 // 2  for Data Cache (for ARMv7 and later, this is Point-of-Coherency threshold.
       
    44 // 4  for XScale AltData Cache.
       
    45 // 8  for Point-of-Unification Data Cache Threshold for ARMv7 and later platforms.
       
    46 // 10 for L2 (L210 or XScale L2 cache)
       
    47 // - "P" "C" & "H" are hex values for purge, clean & flush thresholds.
       
    48 // For example: "t_cache 1 10000 10000 10000" sets 64KB for all thresholds in Instruction Cache.
       
    49 // - t_cache usecase			Runs particular use case tests.
       
    50 // - t_cache help				Displays the list of manual commands.
       
    51 // Platforms/Drives/Compatibility:
