We've noticed that sometimes "MTD do_write_buffer(): software timeout" message was printed out when writing to a Fujitsu NOR flash. It turned out that this was because of a race in the timeout handling do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and sometimes if the timer interrupt handling takes more than one or even two jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just after chip_ready() call, the driver bails out from a ready polling loop despite the chip has actually become ready while all those interrupts were handled. To deal with this issue, extra check for chip ready is neccessary on timeout expiration (and the checks should better be reordered). As do_write_oneword() uses the same approach, it needs to also be changed. Signed-off-by:

The assignement of a "const char *" to a "char *" variable is emitting a warning with gcc 4.0. We cannot change mtd->name to "const char *" as we have dynamic assignements of the name. So casting is the correct solution here Signed-off-by: -

Nathan Roberts noticed the nand_write_ecc index into oobbuf goes out of bounds when crossing an erase block boundary, causing incorrect OOB data to be written and corrupting memory. Reset the index to zero after re-preparing oobbuf for a new erase block. Signed-off-by:

- Use map.virt instead of map.map_priv_1 since it has the correct type. - Use readw/writew instead of dereferencing an ioremap'd cookie. - Remove an unused variable. Signed-off-by:

The Sharp Zaurus akita and borzoi models are large page flash devices. This patch adds support for them to the sharpsl MTD NAND driver but keeps the oob layout and bad block positions compatible with the Sharp Zaurus 2.4 kernel and ROM bootloader. Signed-off-by:

Some callers to block-layer commit_write function treat non-zero return as error, notably the loopback mount driver sometimes used in conjunction with JFFS2 on NAND flash for bad block avoidance, etc. Return zero for success as do various other commit_write functions. Signed-off-by:
