2013-09-09mtd/nand: fsl_nfc: add option for 8-bit wide bus widthMarcel Ziswiler
Add configuration option CONFIG_NAND_FSL_NFC_8BIT to be able to specify narrow 8-bit wide bus width in connecting NAND chips.
2013-09-08NAND Boot:Dan Douglass
- nb_update tool in fsl_nfc driver rewritten to write FCB, BBT, and image to NAND. - vybrid_nand board config added. - NAND read commands added to DCD that force NFC controller to read NAND page twice to prevent NFC hang.

2012-02-28mtd/nand:Fix wrong usage of is_blank() in fsl_ifc_run_commandPrabhakar Kushwaha
Freescale IFC NAND Machine calculates ECC on 512byte sector and same is used in fsl_ifc_run_command() during ECC status verification. Also this sector is passed to is_blank() for blank checking. It is wrong at first place because is_blank()'s implementation checks for Page size and OOB area size. is_blank() should be called per page for main and OOB area verification. Variables name are redefined to avoid confusion between buffer and ecc sector.

2012-02-28nand: reinstate lazy bad block scanningScott Wood
commit 2a8e0fc8b3dc31a3c571e439fbf04b882c8986be ("nand: Merge changes from Linux nand driver") accidentally reverted commit 13f0fd94e3cae6f8a0d9fba5d367e311edc8ebde ("NAND: Scan bad blocks lazily."). Reinstate the change, as amended by commit ff49ea8977b56916edd5b1766d9939010e30b181 ("NAND: Mark the BBT as scanned prior to calling scan_bbt."). Signed-off-by: Scott Wood <scottwood@freescale.com>
2012-02-28Revert "nand: make 1-bit software ECC configurable"Scott Wood
This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5. It breaks boards that currently rely on soft-ecc, as pointed out here: http://patchwork.ozlabs.org/patch/140872/ The reverted patch should be resubmitted with documentation, and with the CONFIG_MTD_ECC_SOFT selected from every board that needs it. We could start by looking at what NAND driver the board selects, and whether that driver ever asks for soft ECC. Signed-off-by: Scott Wood <scottwood@freescale.com>

2012-02-09* Fix: watchdog timed out, if flash blank (0xFF) blocksJens Scharsig (BuS Elektronik)
The current implementation of cfi_flash uses udelay to reset watchdog. If several blocks are blank (0xff filled) the watchdog timed out. The reason is, udelay is never called, if flash device is ready to fast. e.g. mw.w $(copy_addr) FFFF 10000;cp.b $(copy_addr) 10880000 20000 -> watchdog timed out mw.w $(copy_addr) 0000 10000;cp.b $(copy_addr) 10880000 20000 -> watchdog not timed out This patch adds an extra watchdog reset in front of flash ready check.

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.

2011-12-06Fix regression in SMDK6400Simon Schwarz
s3c64xx.c implemented its own nand_read_byte, nand_write_buf and nand_read_buf functions. This provoked a regression when these functions were made public by patch 55f429bb39614a16b1bacc9a8bea9ac01a60bfc8. This deletes these duplicated functions from s3c64xx.c and adds the generic implementations in nand_base.c to the spl Makefile. It also adds -ffcuntion-sections and -gc-sections to the compilation flags of the SPL to avoid errors originating from unused functions in nand_base.c.
