2014-03-20mtd: nand: omap: ecc.correct: omap_elm_correct_data: fix erased-page ↵Pekon Gupta1-52/+33
detection for BCHx_HW ECC schemes As erased-pages do not have ECC stored in their OOB area, so they need to be seperated out from programmed-pages, before doing BCH ECC correction. In current implementation of omap_elm_correct_data() which does ECC correction for BCHx ECC schemes, this erased-pages are detected based on specific marker byte (reserved as 0x00) in ecc-layout. However, this approach has some limitation like; 1) All ecc-scheme layouts do not have such Reserved byte marker to differentiate between erased-page v/s programmed-page. Thus this is a customized solution. 2) Reserved marker byte can itself be subjected to bit-flips causing erased-page to be misunderstood as programmed-page. This patch removes dependency on any marker byte in ecc-layout, instead it compares calc_ecc[] with pattern of ECC-of-all(0xff). This implicitely means that both 'data + oob == all(0xff).

2014-03-10mtd: Fix the behavior of OTP write if there is not enough room for dataChristian Riesch3-7/+30
If a write to one time programmable memory (OTP) hits the end of this memory area, no more data can be written. The count variable in mtdchar_write() in drivers/mtd/mtdchar.c is not decreased anymore. We are trapped in the loop forever, mtdchar_write() will never return in this case. The desired behavior of a write in such a case is described in [1]: - Try to write as much data as possible, truncate the write to fit into the available memory and return the number of bytes that actually have been written. - If no data could be written at all, return -ENOSPC. This patch fixes the behavior of OTP write if there is not enough space for all data: 1) mtd_write_user_prot_reg() in drivers/mtd/mtdcore.c is modified to return -ENOSPC if no data could be written at all. 2) mtdchar_write() is modified to handle -ENOSPC correctly. Exit if a write returned -ENOSPC and yield the correct return value, either then number of bytes that could be written, or -ENOSPC, if no data could be written at all. Furthermore the patch harmonizes the behavior of the OTP memory write in drivers/mtd/devices/mtd_dataflash.c with the other implementations and the requirements from [1]. Instead of returning -EINVAL if the data does not fit into the OTP memory, we try to write as much data as possible/truncate the write.

2014-03-10mtd: gpmi: add subpage read supportHuang Shijie1-0/+96
1) Why add the subpage read support? The page size of the nand chip becomes larger and larger, the imx6 has to supports the 16K page or even bigger page. But sometimes, the upper layer only needs a small part of the page, such as 512 bytes or less. For example, ubiattach may only read 64 bytes per page. 2) We only enable the subpage read support when it meets the conditions: <1> the chip is imx6 (or later chips) which can supports large nand page. <2> the size of ECC parity is byte aligned. If the size of ECC parity is not byte aligned, the calling of NAND_CMD_RNDOUT will fail. 3) What does this patch do? This patch will fake a virtual small page for the subpage read, and call the gpmi_ecc_read_page() to do the real work. In order to fake a virtual small page, the patch changes the BCH registers and the bch_geometry{}. After the subpage read finished, we will restore them back. 4) Performace: 4.1) Tested with Toshiba TC58NVG2S0F(4096 + 224) with the following command: #ubiattach /dev/ubi_ctrl -m 4 The detail information of /dev/mtd4 shows below: -------------------------------------------------------------- #mtdinfo /dev/mtd4 mtd4 Name: test Type: nand Eraseblock size: 262144 bytes, 256.0 KiB Amount of eraseblocks: 1856 (486539264 bytes, 464.0 MiB) Minimum input/output unit size: 4096 bytes Sub-page size: 4096 bytes OOB size: 224 bytes Character device major/minor: 90:8 Bad blocks are allowed: true Device is writable: true -------------------------------------------------------------- 4.2) Before this patch: -------------------------------------------------------------- [ 94.530495] UBI: attaching mtd4 to ubi0 [ 98.928850] UBI: scanning is finished [ 98.953594] UBI: attached mtd4 (name "test", size 464 MiB) to ubi0 [ 98.958562] UBI: PEB size: 262144 bytes (256 KiB), LEB size: 253952 bytes [ 98.964076] UBI: min./max.
