      TPL : introduce the TPL based on the SPL · 3aa29de0
      Ying Zhang authored
      Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can
      not be more than 4K. So, the SPL cannot initialize the DDR with the SPD
      code. This patch introduces TPL to enable a loader stub that is loaded
      by the code from the SPL. It initializes the DDR with the SPD or other
      The TPL's size is sizeable, the maximum size is decided by the memory's
      size that TPL runs. It initializes the DDR through SPD code, and copys
      final uboot image to DDR. So there are three stage uboot images:
      	* spl_boot, * tpl_boot, * final uboot image
