+// Description:
+// e32test\debug\t_cache.cpp
+// Overview:
+// Performs cache checking in order to ensure it is running correctly.
+// Runs automatically or as manual test. (Type "t_cache help" for details.)
+// API Information:
+// class Cache
+// class L2Cache
+// Details:
+// -Test1 - Displays cache properties.
+// -Test2 - Gets thresholds.
+// -Test3 - Sets thresholds.
+// -Test4 - Compares different memory mappings of data.
+// -Test5 - Compares different memory mappings of code.
+// -Test6 - Tests Write Back mode.
+// -Test7 - Tests cache maintenance functions
+// It can also perform more specified tests if run manually:
+// - t_cache info				Test1 only
+// - t_cache data <size_hex>	Runs data chunk test (Test 4) with specified chunk size. For example,
+// "t_cache data 10000" will run data chunk test against 64KB chunk.
+// - t_cache code <size_hex>	Runs code chunk test (Test 5) for specified chink size. For example,
+// "t_cache code 10000" will run code chunk test against 64KB chunk.
+// - t_cache data+<size_hex>	Runs data chunk test for specified set of chunk sizes. For example,
+// "t_cache data+1000" will perform data chunk test for sizes 4K, 8K,... up to 512K.
+// - t_cache code+<size_hex>	Runs code chunk test for specified set of sizes. For example,
+// "t_cache code+1000" will perform code chunk test for sizes 4K, 8K,... up to 512K.
+// - t_cache threshold			Diplays thresholds for all caches on the platform.
+// - t_cache threshold T P C H	Sets new values for cache thresholds:
+// - "T" specifies the type of cache to whose threshould are to be chenged:
+// 1  for Instruction (or Unified) Cache.
+// 2  for Data Cache (for ARMv7 and later, this is Point-of-Coherency threshold.
+// 4  for XScale AltData Cache.
+// 8  for Point-of-Unification Data Cache Threshold for ARMv7 and later platforms.
+// 10 for L2 (L210 or XScale L2 cache)
+// - "P" "C" & "H" are hex values for purge, clean & flush thresholds.
+// For example: "t_cache 1 10000 10000 10000" sets 64KB for all thresholds in Instruction Cache.
+// - t_cache usecase			Runs particular use case tests.
+// - t_cache help				Displays the list of manual commands.
+// Platforms/Drives/Compatibility:
+// Hardware - ARM only (Manual). Not supported on emulator.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
+// d_cache.mmp to be built from the baseport.
