* at91: atmel_nand: extract HWECC initialization code into one function: ↵Wu, Josh2012-09-01-1/+1
| | | | | | | | | | | | atmel_hw_nand_init_param(). This patch 1. extract the hwecc initialization code into one function. It is a preparation for adding atmel PMECC support. 2. enable CONFIG_SYS_NAND_SELF_INIT. Which make us can configurate the ecc parameters between nand_scan_ident() and nand_scan_tail().

* nand/fsl_elbc: Convert to self-initScott Wood2012-01-26-0/+11
| | | | | | | | This driver doesn't yet make use of the added flexibility (not that that should stop anyone from converting...), but it will with the in-progress hack to support 4k-page NAND. Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand: Introduce CONFIG_SYS_NAND_SELF_INITScott Wood2012-01-26-0/+5
| | | | | | | | | | | | | This allows a driver to run code between nand_scan_ident() and nand_scan_tail(), among other things. See the additions to doc/README.nand for details. To allow a gradual transition, Boards that don't set CONFIG_SYS_NAND_SELF_INIT will still be initialized the old way, but new drivers should not require this, and existing drivers should be converted when convenient.

* nand_util: drop trailing all-0xff pages if requestedBen Gardiner2011-07-01-0/+1
| | | | | | | | | | | | | | | | | | | | 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 Gardiner2011-07-01-1/+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 Gardiner2011-07-01-1/+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>

* nand erase: .spread, .part, .chip subcommandsScott Wood2010-10-11-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html, Michele De Candia posted a patch to not count bad blocks toward the requested size to be erased. This is desireable when you're passing in something like $filesize, but not when you're trying to erase a partition. Thus, a .spread subcommand (named for consistency with http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced to make explicit the user's desire to erase for a given amount of data, rather than to erase a specific region of the chip. While passing $filesize to "nand erase" is useful, accidentally passing something like $fliesize currently produces quite unpleasant results, as the variable evaluates to nothing and U-Boot assumes that you want to erase the entire rest of the chip/partition. To improve the safety of the erase command, require the user to make explicit their intentions by using a .part or .chip subcommand. This is an incompatible user interface change, but keeping compatibility would eliminate the safety gain, and IMHO it's worth it. While touching nand_erase_opts(), make it accept 64-bit offsets and sizes, fix the percentage display when erase length is rounded up, eliminate an inconsistent warning about rounding up the erase length which only happened when the length was less than one block (rounding up for $filesize is normal operation), and add a diagnostic if there's an attempt to erase beginning at a non-block boundary.

* NAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB)Ben Gardiner2010-07-12-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a re-submission of the patch by Harald Welte <laforge@openmoko.org> with minor modifications for rebase and changes as suggested by Scott Wood <scottwood@freescale.com> [1] [2]. This patch enables the environment partition to have a run-time dynamic location (offset) in the NAND flash. The reason for this is simply that all NAND flashes have factory-default bad blocks, and a fixed compile time offset would mean that sometimes the environment partition would live inside factory bad blocks. Since the number of factory default blocks can be quite high (easily 1.3MBytes in current standard components), it is not economic to keep that many spare blocks inside the environment partition. With this patch and CONFIG_ENV_OFFSET_OOB enabled, the location of the environment partition is stored in the out-of-band (OOB) data of the first block in flash. Since the first block is where most systems boot from, the vendors guarantee that the first block is not a factory default block. This patch introduces the 'nand env.oob' command, which can be called from the u-boot command line. 'nand env.oob get' reads the address of the environment partition from the OOB data, 'nand env.oob set {offset,partition-name}' allows the setting of the marker by specifying a numeric offset or a partition name.

* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-2/+0
| | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

* NAND: move board_nand_init to nand.hMike Frysinger2009-01-23-0/+2
| | | | | | | | | | | Rather than putting the function prototype for board_nand_init() in the one place where it gets called, put it into nand.h so that every place that also defines it gets the prototype. Otherwise, errors can go silently unnoticed such as using the wrong return value (void rather than int) when defining the function.

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
