* mtd: spi: Fix page size for S25FL032P,S25FL064PMarek Vasut2014-03-17-1/+15
| | | | | | | | | | | | The commit 6af8dc3ebccb3b1e4b2e479315e49545e7f53150 broke support for S25FL032P and S25FL064P by carelessly removing the code handling special page size for these two SPI NOR flashes and unifying the code under the assumption that Extended JEDEC ID of 0x4d00 always implies 512b page size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | chip->ecc.correct() is used for detecting and correcting bit-flips during read operations. In omap-nand driver it implemented as: (a) omap_correct_data(): for h/w based ECC_HAM1 scheme (b) omap_correct_data_bch() + CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW_DETECTION_SW for ECC_BCH8 scheme using GPMC and software lib/bch.c (c) omap_correct_data_bch() + CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW for ECC_BCH8 scheme using GPMC and ELM This patch updates (c) - checks for calc_ecc[]==0x00 so that error_correction is not required for known good pages. - adds scalability for other ECC_BCHx scheme by merging following omap_rotate_ecc_bch() + omap_fix_errors_bch() => omap_correct_data_bch() - fixing logic for bit-flip correction based on error_loc[count] Signed-off-by: Pekon Gupta <pekon@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | chip->ecc.calculate() is used for calculating and fetching of ECC syndrome by processing the data passed during Read/Write accesses. All H/W based ECC schemes use GPMC controller to calculate ECC syndrome. But each BCHx_ECC scheme has its own implemetation of post-processing and fetching ECC syndrome from GPMC controller. This patch updates OMAP_ECC_BCH8_CODE_HW ECC scheme in following way: - merges multiple chip->calculate API for different ECC schemes omap_calculate_ecc() + omap_calculate_ecc_bch() + omap_calculate_ecc_bch_sw() ==> omap_calculate_ecc() - removes omap_ecc_disable() and instead uses it as inline.

|/ | | | | | | | | | | | | | | | | | | chip->ecc.hwctl() is used for preparing the H/W controller before read/write NAND accesses (like assigning data-buf, enabling ECC scheme configs, etc.) Though all ECC schemes in OMAP NAND driver use GPMC controller for generating ECC syndrome (for both Read/Write accesses). But but in current code HAM1_ECC and BCHx_ECC schemes implement individual function to achieve this. This patch (1) removes omap_hwecc_init() and omap_hwecc_init_bch() as chip->ecc.hwctl will re-initializeGPMC before every read/write call. omap_hwecc_init_bch() -> omap_enable_ecc_bch() (2) merges the GPMC configuration code for all ECC schemes into single omap_enable_hwecc(), thus adding scalability for future ECC schemes. omap_enable_hwecc() + omap_enable_ecc_bch() -> omap_enable_hwecc() Signed-off-by: Pekon Gupta <pekon@ti.com>

The problem is that the ffchars[] array is an array of "unsigned char", but in onenand_write_ops_nolock() can be passed to the memcpy_16() function. The memcpy_16() function will treat the buffer as an array of "unsigned short", thus triggering unaligned access if the compiler decided ffchars[] to be not aligned.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we change to software ecc and then back to hardware ecc, the nand ecc ops pointers are populated with incorrect function pointers. This is related to the way nand_scan_tail() handles assigning functions to ecc ops: If we are switching to software ecc/no ecc, it assigns default functions to the ecc ops pointers unconditionally, but if we are switching to hardware ecc, the default hardware ecc functions are assigned to ops pointers only if these pointers are NULL (so that drivers could set their own functions). In the case of omap_gpmc.c driver, when we switch to sw ecc, sw ecc functions are assigned to ecc ops by nand_scan_tail(), and when we later switch to hw ecc, the ecc ops pointers are not NULL, so nand_scan_tail() does not overwrite them with hw ecc functions. The result: sw ecc functions used to write hw ecc data. Clear the ecc ops pointers in omap_gpmc.c when switching ecc types, so that ops which were not assigned by the driver will get the correct default values from nand_scan_tail().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When switching ecc mode, omap_select_ecc_scheme() assigns the appropriate values into the current nand chip's ecc.layout struct. This is done under the assumption that the struct exists only to store values, so it is OK to overwrite it, but there is at least one situation where this assumption is incorrect: When switching to 1 bit hamming code sw ecc, the job of assigning layout data is outsourced to nand_scan_tail(), which simply assigns into ecc.layout a pointer to an existing struct prefilled with the appropriate values. This struct doubles as both data and layout definition, and therefore shouldn't be overwritten, but on the next switch to hardware ecc, this is exactly what's going to happen. The next time the user switches to software ecc, they're going to get a messed up ecc layout. Prevent this and possible similar bugs by explicitly using the private-to-omap_gpmc.c omap_ecclayout struct when switching ecc mode.

Since 1 bit hamming sw ecc is only meant to be used by legacy devices, revert to the original behavior.
