We concluded that the auto-discovery (aka NAND_BUSWIDTH_AUTO) should be the default behavior, since there's no other way to handle ONFI devices. Hence, there's little point in keeping the macro. -- Ezequiel GarcĂ­a, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com
