I'm on an iPAQ h1910 board working with a Samsung NAND 16MiB 3,3V chip
I have a few questions about reading from the out of band area, namely with
reading multiple pages. First off, by reading the spec sheet for this flash
chip, I don't see any information about multiple pages of OOB data. Would it
be called something else?
Secondly, I don't see any code in nanddump or nandwrite to deal with multiple
pages of OOB data. Should there be?
Finally, I'm looking through drivers/mtd/nand/nand.c, and I'm looking at the
particular block that begins with the comment:
* Read the data, if we read more than one page
* oob data, let the device transfer the data !
I see how there's a read command before that. Should that be inside the loop
if we're going to modify col?
