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.

2023-05-30mtd-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.

2022-11-07misc-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.

2021-06-12misc-utils: flashcp: Add new function that copy only different blocksHarvey Wu
- The original flashcp process is erase, write and verify all blocks in one time from file to device. This patch will add a function that only copy different block data from file to device. The function will compare blocks by block between file and device, then erase and write block data from file to device if found different block.

2019-10-28flashcp: Add option -A/--erase-allAndrij Abyzov
Sometimes there's a need to erase the whole device when programming an image, and not just the area under the image itself. Therefore, option -A/--erase-all has been added which erases the whole device before writing the image.

2017-11-02Add no-return attribute to usage() style functionsDavid Oberhollenzer
A common pattern in command line processing is having a usage() function that prints out how to use the command line options and then terminates. The function is typically used inside a switch block for command line options like `-h' or unknown options. In a lot of places, the break keyword is omitted, because the function exits anyway. However, this triggers gcc warnings about implicit fall-through. Rather than adding a phony "/* fall-through */" this patch flags the usage() style function with a gcc attribute, indicating that they do not return and removes further superfluous break statements.

2016-11-17Unify version string printingDavid Oberhollenzer
When a program does sophisticated enough command line processing (i.e. getopt), make sure it responds to -V and --version. When a program prints a version string, make sure it uses the common_print_version macro to print out its name, that it is part of mtd-utils and the mtd-utils version from the build system in a fashion similar to common program packages like the GNU coreutils. When a program responds to -V/--version or -h/--help, make sure it reports success exit status.

filestat.st_size type is off_t. For some paltforms, off_t can be 32 or 64bit but there is no C99 format specifier for off_t. The best way to print it with printf is to cast it to long long and print with %llu Signed-off-by: Fabien Proriol <fabien.proriol@jdsu.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
