[U-Boot] [PATCH 5/8 v3] P1021: add P1021MDS board support

From: Haiying Wang Haiying.Wang@freescale.com

Support P1021MDS board to boot from NAND flash (No NOR flash on this board). And because P1021 only has 256K L2 SRAM, which can not used for final uboot image, this patch also enables the TPL BOOT on P1021MDS so that DDR can be initialized in L2 SRAM through SPD code. So there are three stage uboot images: * nand_spl, pad from 4KB size to 16KB, load tpl_boot from offset 16KB in NAND. * tpl_boot, 112KB size. The env variables are copied to offset 128KB in L2 SRAM, so that ddr spd code can get the interleaving mode setting in env. It loads final uboot image from offset 128KB in NAND. * final uboot image, size is variable depends on the functions enabled.
