2012-09-29mtd: lpc32xx_mlc: Cleanup after DT-only conversionRoland Stigge1-28/+18
The LPC32xx's DT-only conversion of the MLC NAND driver makes NAND config via platform_data obsolete. Dropped by this patch. Further, the driver really needs CONFIG_OF, which is already reflected by the dependency on ARCH_LPC32XX which depends on CONFIG_OF. So also dropping CONFIG_OF ifdefs. There is still platform_data necessary to supply the dma_filter callback for the dma engine. This is a completely different data structure than the old platform_data for NAND config, so renaming some old "pdata" variable to "ncfg" to prevent confusion with the new platform data.

2012-09-29mtd: mtdpart: break it as soon as we parse out the partitionsHuang Shijie1-1/+4
We may cause a memory leak when the @types has more then one parser. Take the `default_mtd_part_types` for example. The default_mtd_part_types has two parsers now: `cmdlinepart` and `ofpart`. Assume the following case: The kernel command line sets the partitions like: #gpmi-nand:20m(boot),20m(kernel),1g(rootfs),-(user) But the devicetree file(such as arch/arm/boot/dts/imx28-evk.dts) also sets the same partitions as the kernel command line does. In the current code, the partitions parsed out by the `ofpart` will overwrite the @pparts which has already set by the `cmdlinepart` parser, and the the partitions parsed out by the `cmdlinepart` is missed. A memory leak occurs. So we should break the code as soon as we parse out the partitions, In actually, this patch makes a priority order between the parsers. If one parser has already parsed out the partitions successfully, it's no need to use another parser anymore.

2012-09-29JFFS2: fix unmount regressionArtem Bityutskiy1-0/+4
This patch fixes regression introduced by "8bdc81c jffs2: get rid of jffs2_sync_super". We submit a delayed work in order to make sure the write-buffer is synchronized at some point. But we do not flush it when we unmount, which causes an oops when we unmount the file-system and then the delayed work is executed. This patch fixes the issue by adding a "cancel_delayed_work_sync()" infocation in the '->sync_fs()' handler. This will make sure the delayed work is canceled on sync, unmount and re-mount. And because VFS always callse 'sync_fs()' before unmounting or remounting, this fixes the issue.

2012-09-29mtd: allow uclinux map driver to be used on any ColdFire CPU platformGreg Ungerer1-1/+1
The uclinux.c map driver has traditionally been used only on non-MMU based systems. But there is no fundamental reason it can't be used on systems running with virtual memory. Some ColdFire CPU based systems now have full paged MMU hardware and can use the uclinux.c mapping driver, so making the uclinux.c driver configuration depend on !CONFIG_MMU doesn't make sense now. Allow the CONFIG_MTD_UCLINUX option to be enabled if CONFIG_COLDFIRE is enabled. (I have chosen not to just more generally allow uclinux.c for any MMU type to keep this option hidden for most systems that are not interested in setting it).

2012-09-29mtd: fix wrong usage of ioremap_nocache() in uclinux.c map driverGreg Ungerer1-6/+9
The uclinux.c mapping driver uses ioremap_nocache() to map its physical mapping address to a system virtual address. Problem is that the region it is mapping is not device memory. It is ordinary system RAM. On most non-MMU systems this doesn't matter, and the mapping is always a 1:1 translation of the address. On paged memory systems on some architectures the page table mappings are not compatible between normal RAM and device memory. If we want to use the uclinux.c mapping driver on real MMU enabled systems we should be using the kernel virtual address that the mapping is at. For architectures that support the traditional initrd they use phys_to_virt or __va to convert the physical start initrd address to a kernel usable virtual address. The uclinux filesystem mapping is even more restrictive than the typical initrd, it always follows the kernels own bss section (so always in directly mapped memory). Therefore we can use the usual phys_to_virt to translate the physical start address to a virtual address.

2012-09-29mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverBrian Norris2-8/+2
The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

2012-09-29mtd: docg4: fix oob readsMike Dunn1-27/+6
This patch does two closely related things: (1) Currently the ecc.read_page() method does not fill the nand->oob_poi buffer with the oob data, but instead reads oob into a local buffer. Fix this by filling the oob_poi buffer instead of a local buffer. The 'oob_required' argument is quietly ignored; the device must always read oob after the page data, and it is presumed that there's no harm in filling oob_poi, even when not explicitly requested. (2) Always read oob from the device in ecc.read_oob(), instead of copying it from a local buffer under some circumstances.

2012-09-29mtd: nand: use ECC, if present, when scanning OOBBrian Norris1-7/+20
scan_read_raw_oob() is used in only in places where the MTD_OPS_PLACE_OOB mode is preferable to MTD_OPS_RAW mode, so use MTD_OPS_PLACE_OOB instead. MTD_OPS_PLACE_OOB provides the same functionality with the potential[1] added bonus of error correction. This brings scan_block_full() in line with scan_block_fast() so that they both read bad block markers with MTD_OPS_PLACE_OOB. This can help in preventing 0xff markers (in good blocks) from being interpreted as bad block indicators in the presence of a single bitflip. Note that ECC error codes (EUCLEAN or EBADMSG) are already silently ignored in all users of scan_read_raw_oob(). [1] Few drivers perform proper error correction on OOB data. In those cases, the use of MTD_OPS_RAW vs. MTD_OPS_PLACE_OOB is not significant.

2012-09-29mtd: check for max_bitflips in mtd_read_oob()Brian Norris1-1/+13
mtd_read_oob() has some unexpected similarities to mtd_read(). For instance, when ops->datbuf != NULL, nand_base.c might return max_bitflips; however, when ops->datbuf == NULL, nand_base's code potentially could return -EUCLEAN (no in-tree drivers do this yet). In any case where the driver might return max_bitflips, we should translate this into an appropriate return code using the bitflip_threshold. Essentially, mtd_read_oob() duplicates the logic from mtd_read(). This prevents users of mtd_read_oob() from receiving a positive return value (i.e., from max_bitflips) and interpreting it as an unknown error. Artem: amend comments.
