During the last months, Boris Brezillon shared his work to support serial flashes within Linux. First, he delivered (and merged) a new layer called spi-mem. He also initiated in Linux MTD subsystem the move of all 'raw' NAND related code to a raw/ subdirectory, adding at the same time a NAND core that would be shared with all NAND devices. Then, he contributed a generic SPI-NAND driver, making use of this NAND core, as well as some vendor code to drive a few chips. On top of this work, I made some cleanups in the MTD layer and added an 'mtd' U-Boot command to handle all sort of MTD devices. This should become the default command instead of having one per flash flavor ('sf', 'nand', 'spi-nand' ?). The series has been tested on an Ocelot board PCB123 (VSC7514), featuring a Macronix SPI NAND chip. TL;DR: the series contains: - A few patches from Linux to resynchronize some areas of the MTD layer. - Various fixes and re-organization of the MTD subsystem. - The introduction of the SPI-mem interface. - The addition of the generic SPI-NAND driver (and its bindings). - Several SPI NAND chip drivers (Macronix, Micron, Winbond). - A new 'mtd' command. - Support for spi-nand devices in mtdparts. To test your SPI-NAND device with U-Boot simply follow these lines: > setenv mtdparts mtdparts=spi-nand0:1m(foo),-(bar) > ubi part bar # create a static UBI volume in the bar partition > mtd list # show the current MTD devices/partitions Thanks, Miquèl Changes since v6: ----------------- * Squashed Boris' fixes about build issues in Travis. * Merged Stefan Roese's contributions. * cmd: mtdparts: * added fallthrough comments in switch blocks deriving sizes. * balanced debug messages to compare freed and allocated partitions. * move mtdparts_init() declaration in mtd/partitions.h to be used in mtd command as well. * introduced a "compatibility" function to return what the MTD device name could be thanks to the mtdids environment variable (which is useless with the new partitioning logic). * mtd: mtdpart: * reworked the way partitions are created/handled. * cmd: mtd: * implement a partitioning logic that takes the best out of the MTD layer without re-inventing the wheel. Partitions are all freed correctly when the value of mtdparts changes. * balance get_mtd_device() by put_mtd_device() calls. * prevent memory leak by reorganizing the code a bit in do_mtd. * do not reconstruct partition list when a partition is already in use (complain about that instead). * add support for the legacy mtdids (not needed anymore if mtdparts directly uses the MTD device names as in Linux. * cmd: ubi: * clean and simplify the partition handling a bit to make use the best use of the MTD layer as well and keep the code simple. Changes since v5: ----------------- * Included Boris fixup about the build issues. * Added Rb/Ab tags from Jagan on patchs 20/21. Changes since v4: ----------------- * Added Jagan's Acked-by tags to every patch related to the SPI-mem/SPI-NAND addition. * Rebased on top of master. Changes since v3: ----------------- * Fixed the debug messages in spi-mem to print either Rx or Tx data. * Fixed a Kconfig error that prevented to build mtdparts with plain defconfig. * Fixed a compilation error due to the above error that prevented one file to be compiled. * Adapted the mtd command to probe MTD partitions also. * Declared mtd_probe_devices() in a header so mtdparts or UBI could use it too (to probe all devices and MTD partitions in a clean way). * As I worked on mtdparts, I found annoying and completely useless the fact that we need to prefix the environment variable with "mtdparts=". Canceled this obligation. * Added one patch to allow spi-nand devices to be recognized by mtdparts (this is purely useless but needed to be done in order to use this command). * Removed useless definitions of MTD device types in UBI code. * Wrote a generic mtdparts environment variable parser, used by the mtd command. * Used the mtd_probe_devices() function from get_mtd_info() in cmd/mtdparts.c to be sure the desired partition really does not exist (otherwise it will be probed and then found). Changes since v2: ----------------- * Rebased on u-boot master branch. * Removed extra-parenthesis in "mtd: Fallback to ->_read/write() when ->_read/write_oob() is missing" * s/fiels/files/ in "mtd: move NAND fiels into a raw/ subdirectory" * Do not describe generic SPI device properties in SPI NAND bindings. * Changes in the mtd command: * Printing more information in 'mtd list' (device type, device characteristics) * Switch to do_div() instead of '(u32)value64b % value32b' which only worked because value32b was a power of 2. * Removed erase.chip option. * By default, erase/read/write happen on the full MTD device while a dump will only work on a single page. Changes since v1: ----------------- * Fixed the nand_memorg structure of the MX35LF2GE4AB chip. * Added Reviewed-by tags from Jagan. * Backported and squashed two patches fixing things in the SPI NAND core received on the Linux ML. * Backported more changes in mtdcore.c from Linux. * Added a patch to add a fallback on mtd->_read/_write() in mtdcore.c when mtd->_read/write_oob() is not supported. * Removed the DT changes, useless as the DTs are not available in mainline yet. * Addressed Boris/Stefan comments on the 'mtd' command. * Added support for multi-pages OOB read/write.
