Dear Huang Shijie,

So we can't stream data from the chip? About time to adjust the MTD
framework to allow that. Maybe implement a command queue?
IMHO, it's not possible. Because the READ-PAGE(00h-30h) command needs to
check the busy status
which means we have to stop in the middle, so we can not chain the all
the read-pages DMA commands.
Can the DMA not branch?
it's too complicated to the MTD layer, as well as the gpmi driver.
Best Regards
Huang Shijie
