28  Fills a target buffer with a 32-bit value, and returns the target buffer.
29
30  This function fills Length bytes of Buffer with the 32-bit value specified by
31  Value, and returns Buffer. Value is repeated every 32-bits in for Length
32  bytes of Buffer.
33
34  If Length > 0 and Buffer is NULL, then ASSERT().
35  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
36  If Buffer is not aligned on a 32-bit boundary, then ASSERT().
37  If Length is not aligned on a 32-bit boundary, then ASSERT().
38
39  @param  Buffer  Pointer to the target buffer to fill.
40  @param  Length  Number of bytes in Buffer to fill.
41  @param  Value   Value with which to fill Length bytes of Buffer.
42
43  @return Buffer.
