For most boards it will be sufficient to provide just the basic functions and fill out some really board dependend members in the nand chip description structure. See drivers/mtd/nand/skeleton for reference.
At least you have to provide a mtd structure and a storage for the ioremap'ed chip address. You can allocate the mtd structure using kmalloc or you can allocate it statically. In case of static allocation you have to allocate a nand_chip structure too.
Kmalloc based example
static struct mtd_info *board_mtd; static unsigned long baseaddr;
Static example
static struct mtd_info board_mtd; static struct nand_chip board_chip; static unsigned long baseaddr;
