2009-09-19mtd: nand: DaVinci: Add 4-bit ECC support for large page NAND chipsSneha Narnakaje
This patch adds 4-bit ECC support for large page NAND chips using the new ECC mode NAND_ECC_HW_OOB_FIRST. The platform data from board-dm355-evm has been adjusted to use this mode. The patches have been verified on DM355 device with 2KiB-page Micron devices using mtd-tests and JFFS2. Error correction up to 4 bits has also been verified using nandwrite/nanddump utilities.

2009-09-19mtd: nand: add new ECC mode - ECC_HW_OOB_FIRSTSneha Narnakaje
This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to support 4-bit ECC on TI DaVinci devices with large page (up to 2KiB) NAND chips. This ECC mode is similar to NAND_ECC_HW, with the exception of read_page API that first reads the OOB area, reads the data in chunks, feeds the ECC from OOB area to the ECC hw engine and perform any correction on the data as per the ECC status reported by the engine.

2009-09-19mtd: nand: add "page" parameter to all read_page/read_page_raw APIsSneha Narnakaje
This patch adds a new "page" parameter to all NAND read_page/read_page_raw APIs. The read_page API for the new mode ECC_HW_OOB_FIRST requires the page information to send the READOOB command and read the OOB area before the data area.

2009-09-19mtd: onenand: make onenand/generic.c more genericMagnus Damm
Remove the ARM dependency from the generic "onenand" platform device driver. This change makes the driver useful for other architectures as well. Needed for the SuperH kfr2r09 board. Apart from the obvious Kconfig bits, the most important change is the move away from ARM specific includes and platform data. Together with this change the only in-tree board code gets an update, and the driver name is also changed gracefully break potential out of tree drivers. The driver is also updated to allow NULL as platform data together with a few changes to make use of resource_size() and dev_name().

2009-09-19mtd: nand: register orion_nand using platform_driver_probe()Uwe Kleine-König
orion_nand_probe lives in .init.text, so using platform_driver_register to register it is wrong because binding a device after the init memory is discarded (e.g. via sysfs) results in an oops. As requested by Nicolas Pitre platform_driver_probe is used instead of moving the probe function to .devinit.text as proposed initially. This saves some memory, but devices registered after the driver is probed are not bound (probably there are none) and binding via sysfs isn't possible.

2009-08-14UBI: improve NOR flash erasure quirkArtem Bityutskiy
More testing of NOR flash against power cuts showed that sometimes eraseblocks may be unwritable, and we cannot really invalidate them before erasure. But in this case the eraseblock probably contains garbage anyway, and we do not have to invalidate the headers. This assumption might be not true, but this is at least what I have observed. So if we cannot invalidate the headers, we make sure that the PEB does not contain valid VID header. If this is true, everything is fine, otherwise we panic.

2009-08-14UBI: print a warning if too many PEBs are corruptedArtem Bityutskiy
There was a bug report recently where UBI prints: UBI error: ubi_attach_mtd_dev: failed to attach by scanning, error -22 error messages and refuses to attach a PEB. It turned out to be a buggy flash driver which returned garbage to almost every UBI read. This patch makes UBI print a better message in such cases. Namely, if UBI finds 8 or more corrupted PEBs, it prints a warning and lists the corrupted PEBs. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-08-14UBI: amend NOR flash pre-erase quirkArtem Bityutskiy
In case of NOR flash, UBI zeroes EC and VID headers' magic, in order to detect interrupted erasures. It first zeroes out the EC magic, then VID magic. However, if a power cut happens in between, we'll end up with a corrupted EC header and a valid VID header, in which case UBI accepts the PEB, but prints a warning. This patch makes sure we first zero out the VID magic, then the EC magic, not vice versa. This is just a small amendment to prevent warning messages.

2009-08-14UBI: print a message if ECH is corrupted and VIDH is okArtem Bityutskiy

2009-08-03mtd: blkdevs: do not forget to get MTD devicesArtem Bityutskiy
Nowadays MTD devices have to be "get" before they can be used. This has to be done with 'get_mtd_device()'. The 'blktrans_open()' function did not do this and instead used 'try_module_get()'. Fix this. Since 'get_mtd_device()' already gets the module, extra 'try_module_get()' is not needed. This fixes oops when one tries to use mtdblock on top of gluebi.
