* nand: Remove CONFIG_MTD_NAND_VERIFY_WRITEPeter Tyser2015-03-30-33/+0
| | | | | | | | | The CONFIG_MTD_NAND_VERIFY_WRITE has been removed from Linux for some time and a more generic method of NAND verification now exists in U-Boot. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Tested-by: Heiko Schocher <hs@denx.de> Acked-by: Heiko Schocher <hs@denx.de>

* mtd: resync with Linux-3.7.1Sergey Lapin2013-05-31-6/+19
| | | | | | | | | | | | | | | | | | | | | | This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

| * Consolidate bool typeYork Sun2013-04-01-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>

* | nand: mxc: Use appropriate page number in syndrome functionsBenoît Thébaudeau2013-04-12-3/+3
| | | | | | | | | | | | | | | | | | | | | | The syndrome functions should use the page number passed as argument instead of the page number saved upon NAND_CMD_READ0. This does not make any difference if the NAND_NO_AUTOINCR option is set, but otherwise this fixes accesses to the wrong pages.

* | mtd: nand: mxc_nand: Fix is_16bit_nand()Fabio Estevam2013-04-12-34/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Currently is_16bit_nand() is a per SoC function and it decides the bus nand width by reading some boot related registers. This method works when NAND is the boot medium, but does not work if another boot medium is used. For example: booting from a SD card and then using NAND to store the environment variables, would lead to the following error: NAND bus width 16 instead 8 bit No NAND device found!!! 0 MiB Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width. If it is defined in the board file, then consider 16-bit NAND bus-width, otherwise assume 8-bit NAND is used. This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which states: nand-bus-width : 8 or 16 bus width if not present 8 Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Reviewed-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>

* mxc_nand: fix a problem writing more than 32MBHelmut Raiger2011-10-03-1/+12
| | | | | | | | | | | | | | 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.
