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.

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. "ECC_HW_OOB_FIRST" name suggested by Thomas Gleixner Reviewed-by:

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. Reviewed-by:

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(). Signed-off-by:

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. Signed-off-by:

This patch fixes a spelling error that has resulted from copy and pasting. The location of the error was found using a semantic patch but the semantic patch was not trying to find these errors.

The function jffs2_nor_wbuf_flash_setup() doesn't allocate the verify buffer if CONFIG_JFFS2_FS_WBUF_VERIFY is defined, so causing a kernel panic when that macro is enabled and the verify function is called. Similarly the jffs2_nor_wbuf_flash_cleanup() must free the buffer if CONFIG_JFFS2_FS_WBUF_VERIFY is enabled. The following patch fixes the problem. The following patch applies to 2.6.30 kernel.

Arithmetic conversion in the mask computation makes the upper word of the second argument passed down to mtd->read_oob(), be always 0 (assuming 'offs' being a 64-bit signed long long type, and 'mtd->writesize' being a 32-bit unsigned int type). This patch applies over the other one adding masking in nftl_write, "nftl: write support is broken". Signed-off-by:

Commit log for commit 517d3cc1 ("[libata] ata_piix: Enable parallel scan") says: This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers. [ Alan: would be better to take the host lock in libata-core for these cases so that we fix all the adapters in one swoop.
