[U-Boot] Is there anyway for configuring NAND and NOR together

Hi All

OMAP3_SDP supports both NAND and NOR flash, depending on the dip switch settings it will select NOR or NAND. So I would like to know is there any way I can configure both NAND and NOR in common configuration file. so that I need not rebuild separatley for NAND or NOR.
