Now that the mtd core supports more then 64 ecc bytes we can use it instead of some a custom hack in the jz4740 nand driver. This patch removes the custom {read,write}_page handlers from the jz4740 nand driver. Thus the driver will now fallback to the default handlers from the nand core.

MTD_OF_PARTS should be possible on all architectures, not just powerpc and microblaze, and it probably should not be a user selectable option. Neither does it need to be in a separate module.

In commit 2a48fc0a ('block: autoconvert trivial BKL users to private mutex'), Arnd replaced the BKL usage with a mutex. However, Maxim has already provided a better fix in commit 480792b7 ('mtd: blktrans: kill BKL'), which was simply to remove the BKL without replacing it — since he'd already made it do all necessary locking for itself.

When system uses 36bit physical address, res.start is 36bit physical address. But the function of in_be32 returns 32bit physical address. Then both of them compared each other is wrong.

RAW writes were broken by 782ce79a which introduced a check of ops->ooboffs in nand_do_write_ops(). When writing in RAW mode this is called with an ops struct on the stack of mtdchar.c:mtd_write() which does not initialise ops->ooboffs, so it is garbage and fails this test. This test does not make sense if ops->oobbuf is NULL, which it is in the RAW write path, so include that in the test.

Now it once again possible to remove mtdtrans module. You still need to ensure that block devices of that module aren't mounted. This is due to the fact that as long as a block device is open, it still exists, therefore if we were to allow module removal, this block device might became used again. This time in addition to code review, I also made the code pass some torture tests like module reload in a loop + read in a loop + card insert/removal all at same time. The blktrans_open/blktrans_release don't take the mtd table lock because: While device is added (that includes execution of add_mtd_blktrans_dev) the lock is already taken Now suppose the device will never be removed. In this case even if we have changes in mtd table, the entry that we need will stay exactly the same. (Note that we don't look at table at all, just following private pointer of block device). Now suppose that someone tries to remove the mtd device. This will be propagated to trans driver which _ought_ to call del_mtd_blktrans_dev which will take the per device lock, release the mtd device and set trans->mtd = NULL. >From this point on, following opens won't even be able to know anything about that mtd device (which at that point is likely not to exist) Also the same care is taken not to trip over NULL mtd pointer in blktrans_dev_release.
