Pekon Gupta eae39cb493 mtd: nand: omap: fix ecclayout to be in sync with u-boot NAND driver ... Fixes: commit a919e51161 mtd: nand: omap2: clean-up BCHx_HW and BCHx_SW ECC configurations in device_probe Fixes ecclayout mismatch introduced in above commit for following ecc-schemes: - OMAP_ECC_BCH4_CODE_HW_DETECTION_SW - OMAP_ECC_BCH8_CODE_HW_DETECTION_SW However, this patch also touches other ecc-schemes as the fix required refactoring common code, into ecc-scheme specific code. This patch aligns ecc-layout for below ecc-schemes as per reference [1],[2],[3] +---+------------+-------------++-------------+-------------+ |OOB|BCH8_CODE_HW|BCH8_CODE_HW_||HAM1_CODE_HW |HAM1_CODE_HW | |pos| | DETECTION_SW||(x8 device) |(x16 device) | +---+------------+-------------++-------------+-------------+ | 0 |BADBLK_MARK | BADBLK_MARK || BADBLK_MARK | BADBLK_MARK | | 1 |BADBLK_MARK | BADBLK_MARK || eccpos[0] | BADBLK_MARK | | 2 | eccpos[0] | eccpos[0] || eccpos[1] | eccpos[0] | | 3 | eccpos[1] | eccpos[1] || eccpos[2] | eccpos[1] | | 4 | eccpos[2] | eccpos[2] || eccpos[3] | eccpos[2] | | 5 | eccpos[3] | eccpos[3] || eccpos[4] | eccpos[3] | | 6 | eccpos[4] | eccpos[4] || eccpos[5] | eccpos[4] | | 7 | eccpos[5] | eccpos[5] || eccpos[6] | eccpos[5] | | 8 | eccpos[6] | eccpos[6] || eccpos[7] | eccpos[6] | | 9 | eccpos[7] | eccpos[7] || eccpos[8] | eccpos[7] | |10 | eccpos[8] | eccpos[8] || eccpos[9] | eccpos[8] | |11 | eccpos[9] | eccpos[9] || eccpos[10] | eccpos[9] | |12 | eccpos[10] | eccpos[10] || eccpos[11] | eccpos[10] | |13 | eccpos[11] | eccpos[11] || oobfree[0] | eccpos[11] | |14 | eccpos[12] | eccpos[12] || oobfree[1] | oobfree[0] | |15 | eccpos[13] | <reserved> || oobfree[2] | oobfree[1] | +---+------------+-------------++-------------+-------------+ |16 | eccpos[14] | eccpos[13] || oobfree[3] | oobfree[2] | |...| [...] | [...] || [...] | [...] | |56 | eccpos[54] | eccpos[51] || oobfree[43] | oobfree[42] | |57 | eccpos[55] | <reserved> || oobfree[44] | oobfree[43] | +===+============+=============+==============+=============+ |58 | oobfree[0] | oobfree[0] || oobfree[45] | oobfree[44] | |59 | oobfree[1] | oobfree[1] || oobfree[46] | oobfree[45] | |60 | oobfree[2] | oobfree[2] || oobfree[47] | oobfree[46] | |61 | oobfree[3] | oobfree[3] || oobfree[48] | oobfree[47] | |62 | oobfree[4] | oobfree[4] || oobfree[49] | oobfree[48] | |63 | oobfree[5] | oobfree[5] || oobfree[50] | oobfree[49] | +---+------------+-------------+--------------+-------------+ [1] ecc-layout expected by ROM code, as specified in SoC TRM under: Chapter="Initialization" Section="Device Initialization by ROM code" Sub-Section="Memory Booting" Heading="NAND" Figure="ECC Locations in NAND Spare Areas" [2] ecc-layout updates in u-boot http://lists.denx.de/pipermail/u-boot/2013-November/167551.html [3] u-boot configurations to match above ecc-layout are documented at https://processors.wiki.ti.com/index.php/Linux_Core_NAND_User%27s_Guide CC: <stable@vger.kernel.org> # 3.13.x+ Reported-by: Enric Balletbo Serra <eballetbo@iseebcn.com> Tested-by: Enric Balletbo i Serra <eballetbo@gmail.com> Tested-by: Stefan Roese <sr@denx.de> Signed-off-by: Pekon Gupta <pekon@ti.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>		2014-02-23 14:49:56 -08:00
