* MPC85xx: remove support for TQM85xx boardsWolfgang Denk2012-10-05-5/+5
| | | | | | | | | | | | Due to grown code sizes the TQM85xx boards don't build any more with some older tool chains (like ELDK 4.2). As these boards have long reached EOL it seems a waste of effort trying to fix them. The vendor has agreed to drop support for them, too. So let's get rid of them.

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.

* at91: atmel_nand: Update driver to support Programmable Multibit ECC controllerWu, Josh2012-09-01-1/+792
| | | | | | | | | | | | | | | | | | The Programmable Multibit ECC (PMECC) controller is a programmable binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use PMECC in this driver, the user needs to set the PMECC correction capability, the sector size and ROM lookup table offsets in board config file. This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference is in this version it uses registers structure access hardware instead of using macros. It is tested in 9x5 serial boards. Signed-off-by: Josh Wu <josh.wu@atmel.com> [rebase] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's set to 256 bytes. When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly the format has changed." No patch has been submitted and the issue was still present. This patch adds the mentioned solution. Tested on a tam3517 board.

* nand/fsl_elbc: Convert to self-initScott Wood2012-01-26-5/+38
| | | | | | | | 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 Wood2012-01-26-37/+59
| | | | | | | | | | | | | 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.

* mtd/nand: Add ONFI support for FSL NAND controllerShengzhou Liu2012-01-26-7/+10
| | | | | | | | - fix NAND_CMD_READID command for ONFI detect. - add NAND_CMD_PARAM command to read the ONFI parameter page. Signed-off-by: Shengzhou Liu <Shengzhou.Liu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand: make 1-bit software ECC configurableChristian Hitz2012-01-26-1/+5
| | | | | | | | | | The software ECC algorithm is not necessary when hardware ECC is available and can be left out for a smaller image size. Enable with CONFIG_MTD_ECC_SOFT.
