+==========================================

+Since the size of SPL can't be exceeded 0x8000 bytes in RK3288, it is not possible add

+
+So introduce TPL so-that adding new features to SPL is possible because now TPL should
+run minimal with code like DDR, clock etc and rest of new features in SPL.
+
+As of now TPL is added on Vyasa-RK3288 board.
