Date: Fri, 3 May 2013 14:21:40 +0800 From: Huang Shijie <b32955@...escale.com> To: <dwmw2@...radead.org> CC: <dedekind1@...il.com>, <computersforpeace@...il.com>, <linux-mtd@...ts.infradead.org>, <linux-kernel@...r.kernel.org>, Huang Shijie <b32955@...escale.com> Subject: [PATCH 0/4] Export the ecc step size to user applications In order to implement the NAND boot for some Freescale's chips, such as imx23/imx28/imx50/imx6, we use a tool (called kobs-ng) to burn the uboot and some metadata to nand chip. And the ROM code will use the metadata to configrate the BCH, and to find the uboot. The ECC information(ecc step size, ecc strength) which is used to configrate the BCH is part of the metadata. The kobs-ng can gets the ecc strength from the sys node /sys/*/mtdX/ecc_strength now. But it can't gets the ecc step size. This patch set is used to export the ecc step size to user applications. With this patch set, the kobs-ng can gets the ecc step size now. Huang Shijie (4): mtd: add a new field to mtd_info{} mtd: add a new sys node to show the ecc step size mtd: set the ecc step size for master/slave mtd_info mtd: gpmi: update the ecc step size for mtd_info{} drivers/mtd/mtdcore.c | 11 +++++++++++ drivers/mtd/mtdpart.c | 1 + drivers/mtd/nand/gpmi-nand/gpmi-nand.c | 1 + drivers/mtd/nand/nand_base.c | 1 + include/linux/mtd/mtd.h | 3 +++ 5 files changed, 17 insertions(+), 0 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
