2023-11-13mtd-utils: flash_erase: Add an option for JFFS2 cleanmarker sizeTakahiro Kuwano
JFFS2 supports buffer mode for ECC'd NOR Flash that cleanmarker size is rounded up to mtd->writesize, while the '-j' option in flash_erase utility uses fixed 12 bytes. That makes flash program ops unaligned to mtd->writesize and causes program error or disables ECC. The mkfs.jffs2 utility supports '-c' option that allows users to specify cleanmarker size. This patch implements '-c' option in the flash_erase that can be used along with '-j' option.

2023-09-08flashcp: Add write last option.Piotr Esden-Tempski
This option is useful for power fail resilient bootloader updates, for systems that check only the partition header for validity before attempting to load the bootloader. For example zynq. Postponing the write of a specified amount of bytes at the beginning of a bootloader makes sure a written bootloader slot is not considered valid until all the data is written.

2023-09-03Pull the bulk of the pre 2.0.0 changes from the git treeDavid Oberhollenzer
For the most part, this was straight forward. For the very old releases, there were lots of changes that are not straight forward to untangle. The following two releases posed issues: - Version 1.4.1 does not have a tag. The release tarball on FTP is from 2010-10-19 and appears to contain 1.4.0 with commit b864c387e8f16273aad1453d6457d847e29c3d25 cherry-picked on top of it (except for one line that was fixed in the release, but broken in the repo). - Version 1.4.6 also does not have a tag. The release tarball is from 2011-08-19. This _presumably_ corresponds with commit b602ab59b9782003d1179488d8c1580bc8563738 that bumps the version number.

In nandflipbits, nandtest and ubiscan, uint64_t integers are printed to stdout using "%llu" as a format specifier, but on platforms like x86_64, uint64_t is actually typedef'd as `unsigned long` only.

Running nandtest on devices with sizes of 4Gb or more does not work, as the size returned in mtd_info_user is reported as 0 for 4Gb devices for example. The patch uses sysfs to figure out the size of the nand device (as recommended in a comment in include/mtd/mtd-abi.h) and changes sizes and offsets to 64 bit values.

2023-05-30mtd-utils: Add new syntax to get devices by nameBrandon Maier
This introduces a new feature to the MTD command line utilities that allows MTD devices to be referenced by name instead of device node. For example this looks like: > # Display info for the MTD device with name "data" > mtdinfo mtd:data > # Copy file to MTD device with name "data" > flashcp /my/file mtd:data This follows the syntax supported by the kernel which allows MTD device's to be mounted by name[1]. Add the function mtd_find_dev_node() that accepts an MTD "identifier" and returns the MTD's device node. The function accepts a string starting with "mtd:" which it treats as the MTD's name. It then attempts to search for the MTD, and if found maps it back to the /dev/mtdX device node. If the string does not start with "mtd:", then assume it's the old style and refers directly to a MTD device node. The function is then hooked into existing tools like flashcp, mtdinfo, flash_unlock, etc. To load in the new MTD parsing code in a consistent way across programs.

2022-11-18mtd-utils: flash_speed: Measure read while write latencyMiquel Raynal
The Read While Write (RWW) feature allows to perform reads from the flash array into cache while a program (from cache) or an erase operation happens, provided that the two areas are located on different banks. The main benefit is the possible reduced latency when requesting to read a page while a much longer operation is ongoing, like a write or an erase. We can try to compare the positive impact of such a feature by enhancing the flash_speed test tool with the following test: - Measure the time taken by an eraseblock write in parallel with an eraseblock read. - Measure when the read operation ends. - Compare the two to get the latency saved with the RWW feature. To be sure the mtd_write actually starts (and acquires the necessary locks) before the mtd_read does, we use SCHED_FIFO at rather high (arbitrary) priorities, respectively 42 and 41.

2022-11-07misc-utils: flashcp: fix buffer overflowBrandon Maier
The DIFF_BLOCKS code requires that src and dest buffers be large enough to hold one MTD erasesize. This is because each loop operates on one eraseblock so that it can erase and write one whole sector. But the src and dest buffers are fixed at BUFSIZE, so on platforms where the MTD erasesize are larger then BUFSIZE it will overflow the buffers. Instead allocate the buffers dynamically so that they can be sized to fit the erasesize.

2022-09-27libmtd: do not ignore non-zero eraseblock size when MTD_NO_ERASE is setEnrico Jorns
In 54d68799, mtd->eb_cnt was enforced to be '1' if MTD_NO_ERASE is set. This was done with the aim of preventing divisions by zero. However, even if MTD_NO_ERASE is set, mtd->eb_size (eraseblock size) can still be set to a non-zero value which would not cause a division by zero. Instead, enforcing an eraseblock count of '1' here even leads to inconsistent eraseblock counting in mtd-utils and lets for example a 'flash_erase' on an mtdnand device fail: | # flash_erase /dev/mtd0 0 0 | Erasing 32768 Kibyte @ 0 -- 0 % complete libmtd: error!: bad eraseblock number 255, mtd0 has 1 eraseblocks | flash_erase: error!: /dev/mtd0: MTD Erase entire chip failureTrying one by one each sector. | error 22 (Invalid argument) | Erasing 128 Kibyte @ 0 -- 0 % complete libmtd: error!: bad eraseblock number 1, mtd0 has 1 eraseblocks | flash_erase: error!: /dev/mtd0: MTD get bad block failed | error 22 (Invalid argument) Also mtdinfo would look inconsistent (eraseblock size vs amount): | # mtdinfo /dev/mtd0 | mtd0 | Name: mtdram test device | Type: ram | Eraseblock size: 131072 bytes, 128.0 KiB | Amount of eraseblocks: 1 (33554432 bytes, 32.0 MiB) | Minimum input/output unit size: 1 byte | Sub-page size: 1 byte | Character device major/minor: 90:0 | Bad blocks are allowed: false | Device is writable: true Fix this by enforcing mtd->eb_cnt to be '1' only when mtd->eb_size is actually zero and would lead to a division by zero otherwise.

Of course if the controller does not support subpages, this issue is not visible.
