2022-06-29mtd: mxs_nand_spl: fix nand_command protocol violationAndrea Scian
mxs_nand_command() implementation assume that it's working with a LP NAND, which is a common case nowadays and thus uses two bytes for column address. However this is wrong for NAND_CMD_READID and NAND_CMD_PARAM, which expects only one byte of column address, even for LP NANDs. This leads to ONFI detection problem with some NAND manufacturer (like Winbond) but not with others (like Samsung and Spansion) We fix this with a simple workaround to avoid the 2nd byte column address for those two commands. Also align the code with nand_base to support 16 bit devices. Tested on an iMX6SX device with: * Winbond W29N04GVSIAA * Spansion S34ML04G100TF100 * Samsung K9F4G08U00 Tested on imx8mn device with: * Windbond W29N04GV Signed-off-by: Andrea Scian <[email protected]> CC: Stefano Babic <[email protected]> Signed-off-by: Michael Trimarchi <[email protected]> Reviewed-by: Fabio Estevam <[email protected]>

2022-05-23spi: spi_flash_probe_bus_cs() rely on DT for spi speed and modePatrice Chotard
Now, spi_flash_probe_bus_cs() relies on DT for spi speed and mode and logically calls spi_get_bus_and_cs(). In case spi mode and speed are not read from DT, make usage of spi_flash_probe() instead. To sum-up: - Previous call tree was: spi_flash_probe() -> spi_flash_probe_bus_cs() -> spi_get_bus_and_cs() - Current call tree is: spi_flash_probe() -> _spi_get_bus_and_cs() spi_flash_probe_bus_cs() -> spi_get_bus_and_cs() This patch impacts the following : - cmd/sf.c: if spi mode and/or speed is passed in argument of do_spi_flash_probe(), call spi_flash_probe() otherwise call spi_flash_probe_bus_cs(). - drivers/net/fm/fm.c: as by default spi speed and mode was set to 0 and a comment indicates that speed and mode are read from DT, use spi_flash_probe_bus_cs(). - drivers/net/pfe_eth/pfe_firmware.c: spi speed and mode are not read from DT by all platforms using this driver, so keep legacy and replace spi_flash_probe_bus_cs() by spi_flash_probe(); - drivers/net/sni_netsec.c : spi speed and mode are not read from DT, so replace spi_flash_probe_bus_cs() by spi_flash_probe(). - drivers/usb/gadget/max3420_udc.c: Can't find any platform which make usage of this driver, nevertheless, keep legacy and replace spi_get_bus_and_cs() by _spi_get_bus_and_cs(). - env/sf.c: a comment indicates that speed and mode are read from DT.

2022-05-20mtd: nand: mxs_nand_spl: Fix bad block skippingMichael Trimarchi
The specific implementation was having bug. Those bugs are since the beginning of the implementation. Some manufactures can already experience this bug in their SPL code. This bug can be more visible on architecture that has complicated boot process like imx8mn. Older version of uboot can be affected if the bad block appear in correspoding of the beginning of u-boot image. In order to adjust the function we scan from the first erase block. The problematic part of old code was in this part: while (is_badblock(mtd, offs, 1)) { page = page + nand_page_per_block; /* Check i we've reached the end of flash. */ if (page >= mtd->size >> chip->page_shift) { free(page_buf); return -ENOMEM; } } Even we fix it adding increment of the offset of one erase block size , we don't fix the problem, because the first erase block where the image start is not checked. The code was tested on an imx8mn where the boot rom api was not able to skip it.

The mxs_nand_spl driver can support to read from page unaligned offset, so don't need to set bl_len to ask spl_load_simple_fit to handle the page unaligned access. Actually spl_load_simple_fit has two parts of reading: spl_simple_fit_read and spl_load_fit_image. The spl_load_fit_image can handle the page unaligned offset, but the spl_simple_fit_read can't do it. spl_simple_fit_read requires the FIT location at page aligned offset. Hence, remove the nand_get_mtd overwrite function from mxs_nand_spl to use page unaligned read by driver.

2022-04-11mtd: Add flash_node in struct mtd_infoPatrice Chotard
Currently, add_mtd_partitions_of() can be used only if dev field of mtd_info struct is populated. It's the case, for example, for a spi nor flash, which has a DT compatible "jedec,spi-nor" and an associated device. mtd->dev is populated in spi_nor_scan(). But in case of a raw nand node, mtd_info's dev field can't be populated as flash node has no compatible, so no associated device. add_mtd_partitions_of() can't be used to parse "partitions" subnode. To remove this constraint, add an ofnode field in mtd_info struct which reference the DT flash node. This new field is populated by nand_scan_tail(). This new field will be used by add_mtd_partitions_of() to parse the flash node for "partitions" defined in DT.

2022-01-16nand: gpmc: Handle bitflips in erased pages when using BCH ECC engineDavid Rivshin
In the case of an erased (sub)page both the data and ECC are all 0xFF bytes. This fails the normal ECC verification, as the computed ECC of all-0xFF is not also 0xFF. The GPMC NAND driver attempted to detect erased pages by checking that the ECC bytes are all-0xFF, but this had two problems: 1) bitflips in the data were not corrected, so the data looked not-erased 2) bitflips in the ECC bytes were reported as uncorrectable ECC errors The equivalent Linux driver [1] correctly handles this by counting the number of 0-bits in the combination of data and ECC bytes. If the number of 0-bits is less than the amount of bits correctable by the selected ECC algorithm, then it is treated as an erased page with correctable bitflips. Implement similar, though simplified, logic in omap_correct_data_bch(). [1] see omap_elm_correct_data() in omap2.c Signed-off-by: David Rivshin <[email protected]>

2022-01-14mtd: nand: pxa3xx: use marvell, prefix for custom DT propertiesPierre Bourdon
The DT properties for the "enable-arbiter" and "keep-config" config knobs were previously named inconsistently: - The u-boot driver used "nand-enable-arbiter" and "nand-keep-config" names, without Marvell prefixes. - The Linux driver uses "marvell,nand-keep-config" ("enable-arbiter" does not exist anymore in recent kernels, but it also used to be "marvell,nand-enable-arbiter"). - The device trees almost all use "marvell," prefixed names, except for one single instance of "nand-enable-arbiter" without vendor prefix. This commit standardizes on the vendor prefixed version, making the u-boot driver read from DT props "marvell,nand-enable-arbiter" and "marvell,nand-keep-config". The one device tree using the unprefixed version is also changed to use the new naming. This has the side effect of making the previously no-op "marvell," config knobs already present in some DTs actually do something. This was likely the original intention of the DT authors, but note that this commit was not tested on every single impacted board. Signed-off-by: Pierre Bourdon <[email protected]>
