| * | UBI: init eba tables before wl when attaching a deviceHolger Brunck2011-10-12-6/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes that u-boot gets stuck when a bitflip was detected during "ubi part <ubi_device>". If a bitflip was detected UBI tries to copy the PEB to a different place. This needs that the eba table are initialized, but this was done after the wear levelling worker detects the bitflip. So changes the initialisation of these two tasks in u-boot. This is a u-boot specific patch and not needed in the linux layer, because due to commit 1b1f9a9d00447d UBI: Ensure that "background thread" operations are really executed we schedule these tasks in place and not as in linux after the inital task which schedule this new task is finished.

* | NAND: davinci: choose correct 1-bit h/w ECC regLaurence Withers2011-10-10-13/+13
|/ | | | | | | | | | | | | | | | | | | In nand_davinci_readecc(), select the correct NANDF<n>ECC register based on CONFIG_SYS_NAND_CS rather than hardcoding the choice of NANDF1ECC. This allows 1-bit hardware ECC to work with chip select other than CS2. Note this now matches the usage in nand_davinci_enable_hwecc(), which already had the correct handling, and allows refactoring to a single function encapsulating the register read. Without this fix, writing NAND pages to a chip not wired to CS2 would result in in the ECC calculation always returning FFFFFF for each 512-byte segment, and reading back a correctly written page (one with ECC intact) would always fail. With this fix, the ECC is written and verified correctly. Signed-off-by: Laurence Withers <lwithers@guralp.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When writing 0x4000 to the unlockend_blkaddr register, large writes to a 2k page NAND sometimes fail. The current kernel driver writes 0xFFFF to this register for V2 of the nand controller. However on an i.MX31 this also fixes writes larger than 32MB. The datasheet is very unspecific, but (0x4000=16384)*2000 roughly fits the limits we're encountering with NAND writes. This problem might be NAND chip specific.

Note that using hardware ECC on IFC with small-page NAND (which is what comes on the p1010rdb reference board) means there will be insufficient OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should work, as it does not use OOB for anything but ECC. When hardware ECC is not enabled in CSOR, software ECC is now used.

| | | | | | | | | | | | | | | | | | | This patch adds support for 16 bit NAND devices attached to the NDFC on ppc4xx processors. Two config entries were added: CONFIG_SYS_NDFC_16 - Setting this tells the NDFC that a 16 bit device is attached. CONFIG_SYS_NDFC_EBC0_CFG - This is for the External Bus Controller configuration register. Also, a new ndfc_read_byte() function was added which does not first convert the data to little endian. The NAND SPL was also modified to do 16bit bad block testing when a 16 bit chip is being used. Signed-off-by: Alex Waterman <awaterman@dawning.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand_util: drop trailing all-0xff pages if requestedBen Gardiner2011-07-01-3/+37
| | | | | | | | | | | | | | | | | | | | Add a flag to nand_read_skip_bad() such that if true, any trailing pages in an eraseblock whose contents are entirely 0xff will be dropped. The implementation is via a new drop_ffs() function which is based on the function of the same name from the ubiformat utility by Artem Bityutskiy.

* nand_util: treat WITH_YAFFS_OOB as a modeBen Gardiner2011-07-01-0/+3
| | | | | | | | | | | | | When specified in the flags argument of nand_write, WITH_YAFFS_OOB causes an operation which is mutually exclusive with the 'usual' way of writing. Add a check that client code does not specify WITH_YAFFS_OOB along with any other flags and add a comment indicating that the WITH_YAFFS_OOB flag should not be mixed with other flags.

* nand_util: convert nand_write_skip_bad() to flagsBen Gardiner2011-07-01-4/+4
| | | | | | | | | | | | | | | | | | | | | | In a future commit the behaviour of nand_write_skip_bad() will be further extended. Convert the only flag currently passed to the nand_write_ skip_bad() function to a bitfield of only one allocated member. This should avoid an explosion of int's at the end of the parameter list or the ambiguous calls like nand_write_skip_bad(info, offset, len, buf, 0, 1, 1); nand_write_skip_bad(info, offset, len, buf, 0, 1, 0); Instead there will be: nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB | WITH_OTHER); Signed-off-by: Ben Gardiner <bengardiner@nanometrics.ca> Acked-by: Detlev Zundel <dzu@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>
