If there is an error detected by a subtest, the test stops and the* failure code is returned. Further tests are not run even if all of the tests* are selected.** Subtest descriptions:* <pre>* XUT_ALLMEMTESTS:*       Runs all of the following tests** XUT_INCREMENT:*       Incrementing Value Test.*       This test starts at 'XUT_MEMTEST_INIT_VALUE' and uses the incrementing*       value as the test value for memory.** XUT_WALKONES:*       Walking Ones Test.*       This test uses a walking '1' as the test value for memory.*       location 1 = 0x00000001*       location 2 = 0x00000002*       ...** XUT_WALKZEROS:*       Walking Zero's Test.*       This test uses the inverse value of the walking ones test*       as the test value for memory.*       location 1 = 0xFFFFFFFE*       location 2 = 0xFFFFFFFD*       ...** XUT_INVERSEADDR:*       Inverse Address Test.*       This test uses the inverse of the address of the location under test*       as the test value for memory.** XUT_FIXEDPATTERN:*       Fixed Pattern Test.*       This test uses the provided patters as the test value for memory.*       If zero is provided as the pattern the test uses '0xDEADBEEF".* </pre>** <i>WARNING</i>** The tests are <b>DESTRUCTIVE</b>. Run before any initialized memory spaces* have been set up.** The address, Addr, provided to the memory tests is not checked for* validity except for the XNULL case. It is possible to provide a code-space* pointer for this test to start with and ultimately destroy executable code* causing random failures.** @note** Used for spaces where the address range of the region is smaller than* the data width. If the memory range is greater than 2 ** width,* the patterns used in XUT_WALKONES and XUT_WALKZEROS will repeat on a* boundry of a power of two making it more difficult to detect addressing* errors. The XUT_INCREMENT and XUT_INVERSEADDR tests suffer the same* problem. Ideally, if large blocks of memory are to be tested, break* them up into smaller regions of memory to allow the test patterns used* not to repeat over the region tested.** <pre>* MODIFICATION HISTORY:** Ver    Who    Date    Changes* ----- ---- -------- -----------------------------------------------* 1.00a ecm  11/01/01 First release* </pre>*******************************************************************************/#ifndef XUTIL_H /* prevent circular inclusions */#define XUTIL_H /* by using protection macros *//***************************** Include Files *********************************/#include "xbasic_types.h"#include "xstatus.h"/************************** Constant Definitions *****************************//**************************** Type Definitions *******************************//* xutil_memtest defines */#define XUT_MEMTEST_INIT_VALUE  1/** @name Memory subtests * @{ *//** See the detailed description of the subtests in the file description. */#define XUT_ALLMEMTESTS     0#define XUT_INCREMENT       1#define XUT_WALKONES        2#define XUT_WALKZEROS       3#define XUT_INVERSEADDR     4#define XUT_FIXEDPATTERN    5#define XUT_MAXTEST         XUT_FIXEDPATTERN/*@}*//***************** Macros (Inline Functions) Definitions *********************//************************** Function Prototypes ******************************//* xutil_memtest prototypes */XStatus XUtil_MemoryTest32(Xuint32 *Addr, Xuint32 Words, Xuint32 Pattern,                           Xuint8 Subtest);XStatus XUtil_MemoryTest16(Xuint16 *Addr, Xuint32 Words, Xuint16 Pattern,                           Xuint8 Subtest);XStatus XUtil_MemoryTest8(Xuint8 *Addr, Xuint32 Words, Xuint8 Pattern,                          Xuint8 Subtest);#endif            /* end of protection macro */
