powerpc: p1010rdb: Enable p1010rdb to start from NAND/SD/SPI flash with SPL
In the previous patches, we introduced the SPL/TPL fraamework. For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The SPL was loaded by the code from the internal on-chip ROM. The SPL initializes the DDR according to the SPD and loads the final uboot image into DDR, then jump to the DDR to begin execution. For NAND booting way, the nand SPL has size limitation on some board(e.g. P1010RDB), it can not be more than 8KB, we can call it "minimal SPL", So the dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD and loads the final uboot image into DDR,then jump to the DDR to begin execution. This patch enabled SPL/TPL for P1010RDB to support starting from NAND/SD/SPI flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL. Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to execute, so the section .resetvec is no longer needed.
