2		For most boards it will be sufficient to provide just the
3		basic functions and fill out some really board dependent
4		members in the nand chip description structure.

6			At least you have to provide a mtd structure and
7			a storage for the ioremap'ed chip address.
8			You can allocate the mtd structure using kmalloc
9			or you can allocate it statically.
10			In case of static allocation you have to allocate
11			a nand_chip structure too.
