The MAX_BIT of EBC will no longer be fixed to bit 63. It is defined as (1ULL << (sizeof (INTN) * 8 - 1)). Make EdkModulePkg & MdePkg EBC compiler clean: treat all EFI_STATUS error code as variable. 2. PrintLib Complete all missing ASSERT()s. Fix “\n” & “%\n” issue thanks to the clarification of MWG 0.56d. Adjust StatusString array to support EBC build. 3. BaseMemoryLib Adjust ASSERT () & function header of ComparaMem, SetMemXX, ScanMemXX to synchronize with MWG 0.56d. 4.SmbusLib Change Pec bit to bit 22 SmBusAddress to synchronize MWG 0.56d. Add ASSERT()s to check if length is illegal for SmBusBlockWrite() & SmBusProcessBlock() since it is 6 bit now. 5. PerformanceLib Rename “EdkDxePerformanceLib” & “EdkPeiPerformanceLib” to “DxePerformanceLib” & “PeiPerformanceLib” respectively. Synchronize the function header of GetPerformanceMeasurement() with MWG 0.56d. 6. BasePeCoffLoaderLib. Make PeCoffLoaderLoadImage () Assert() if ImageContext is NULL> Make PeCoffLoaderLoadImage () return RETURN_INVALID_PARAMETER if the ImageAddress in ImageContext is 0. Adjust some coding style. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@593 6f19259b-4bc3-4df7-8a09-765794883524

/**
|

Scans a target buffer for a 16-bit value, and returns a pointer to the matching 16-bit value
|
||
in the target buffer.
|
||
|
||
This function searches target the buffer specified by Buffer and Length from the lowest
|
||
address to the highest address for a 16-bit value that matches Value. If a match is found,
|
||
then a pointer to the matching byte in the target buffer is returned. If no match is found,
|
||
then NULL is returned. If Length is 0, then NULL is returned.
|
||
If Length > 0 and Buffer is NULL, then ASSERT().
|
||
If Buffer is not aligned on a 16-bit boundary, then ASSERT().
|
||
If Length is greater than (MAX_ADDRESS – Buffer + 1), then ASSERT().
|

@param Buffer Pointer to the target buffer to scan.

@param Length Number of bytes in Buffer to scan.

@param Value Value to search for in the target buffer.

@return A pointer to the matching byte in the target buffer or NULL otherwise.
