Supports boot up from NAND flash with software ECC eanbled. And supports boot up from SD/MMC card with FAT file system. As the boot from SD/MMC card with FAT file system, the BSS segment is too big to fit into SRAM, so, use the lds to put it into SDRAM. Signed-off-by: Bo Shen <voice.shen@atmel.com>
