+  Fills a target buffer with a value that is size UINTN, and returns the target buffer.
+
+  This function fills Length bytes of Buffer with the UINTN sized value specified by
+  Value, and returns Buffer. Value is repeated every sizeof(UINTN) bytes for Length
+  bytes of Buffer.
+
+  If Length > 0 and Buffer is NULL, then ASSERT().
+  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
+  If Buffer is not aligned on a UINTN boundary, then ASSERT().
+  If Length is not aligned on a UINTN boundary, then ASSERT().
+
+  @param  Buffer  The pointer to the target buffer to fill.
+  @param  Length  The number of bytes in Buffer to fill.
+  @param  Value   The value with which to fill Length bytes of Buffer.
+
