> 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
> operations.
>
> 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
>
> This patch is on top of the patch:
> SPL: Makefile: Build a separate autoconf.mk for SPL

These two lines are removed when applying.
