The setting NAND_NO_SUBPAGE_WRITE in omap_nand_platform_data is not used. I am using SLC NAND - MT29F1G16ABC , which seems not to support subpages. I can observe that kernel allows sub-page-writes. I tried to find out what is happend with the options, but after a while I get lost in numerous copies of structs ... Options are still correct in beginning of omap_nand_probe but finally it ends up in setting its option independent from platform options. info->nand.options |= NAND_SKIP_BBTSCAN; if ((gpmc_cs_read_reg(info->gpmc_cs, GPMC_CS_CONFIG1) & 0x3000) == 0x1000) info->nand.options |= NAND_BUSWIDTH_16; This observations are done in a plain vanilla 2.6.33 kernel on an OMAP3 board. Can someone confirm that and know how to change that in a clean way? -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
