I think we should change this a little bit. Unluckily I don't know what is the best way to fix it. As far as I have understood, the NAND_NO_SUBPAGE_WRITE is a chip option, not for a driver.
At nand_base.c is chip->options &= ~NAND_CHIPOPTIONS_MSK; chip->options |= type->options & NAND_CHIPOPTIONS_MSK; so the bit is masked out anyway and subpages are enabled.
After that UBI tries to read VID header at 512 by default. I had to use "ubi part root 2048" to override it. Besides of that driver seems to work fine.
