EMIF supports large block NAND devices, therefore you can have u-boot and Linux Kernel support these large block NAND devices. However, please note that if you plan on booting from NAND device, ROM Boot Loader (RBL) only support booting from NAND devices listed in the ARM Subsystem Guide ( http://focus.ti.com/lit/ug/sprufb3/sprufb3.pdf ).
