* mtd: fsmc_nand: Add BCH4 SW ECC support for SPEAr600Stefan Roese2015-10-261-0/+6
| | | | | | | | | | | | | | | | | | | | | This patch adds support for 4-bit ECC BCH4 for the SPEAr600 SoC. This can be used by boards equipped with a NAND chip that requires 4-bit ECC strength. The SPEAr600 HW ECC only supports 1-bit ECC strength. To enable SW BCH4, you need to specify this in your nand controller DT node: nand-ecc-mode = "soft_bch"; nand-ecc-strength = <4>; nand-ecc-step-size = <512>; Tested on a custom SPEAr600 board.

* ARM: nomadik: add FSMC NANDLinus Walleij2013-01-281-1/+1
| | | | | | | | | | | | | | | This adds the FSMC NAND driver and flash partitions to the Nomadik device tree. The only compatible string accepted by this driver is currently "st,spear600-fsmc-nand" which is inappropriate for this system, so this patch adds the compatible value "stericsson,fsmc-nand" as well.

| | | | | | | | | | | | Do not use the platform_data to pass resource and be smart in the drivers. Just pass it via resource Switch to devm_request_and_ioremap at the sametime Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-By: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
* mtd: Add device-tree support to fsmc_nandStefan Roese2012-03-271-0/+33
This patch adds support to configure the FSMC NAND driver (used amongst others on SPEAr platforms) via device-tree instead of platform_data.
