MTD device structure
NAND chip structure
startpage inside the chip, must be called with (page & this->pagemask)
out of band data buffer
out of band selecttion structre
1 = enable cached programming if supported by chip
Nand_page_program function is used for write and writev ! This function will always program a full page of data If you call it with a non page aligned buffer, you're lost :)
Cached programming is not supported yet.
