If I do that I get the below error.
I think it is because SPL_NAND is being enabled but not required for K2?
Are all options in ti/common/Kconfig relevant for K2?

  CC      spl/common/spl/spl_nand.o
common/spl/spl_nand.c: In function 'spl_nand_load_image':

  err = spl_nand_load_element(spl_image, CONFIG_SYS_NAND_U_BOOT_OFFS,
