mtd-utils.git/misc-utils/mtdpart.c, branch v2.3.1A mirror of http://git.infradead.org/mtd-utils.githttps://git.infraroot.at/mtd-utils.git/atom?h=v2.3.12023-05-30T09:12:12+00:00mtd-utils: Add new syntax to get devices by name2023-05-30T09:12:12+00:00Brandon Maierbrandon.maier@collins.com2022-12-12T18:01:58+00:00urn:sha1:730148bc94411f13a0171204e872b0760fbde185
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.

misc-utils: mtdpart: document partition of size 02022-11-07T07:28:49+00:00Brandon Maierbrandon.maier@collins.com2022-11-03T14:12:17+00:00urn:sha1:4a84311e4706da5823e20db107809a334708e171
If the partition size passed in to the BLKPG_ADD_PARTITION ioctl is 0,
Linux will make the partition fill to the end of the device[1]. Document
this feature in the help.

This commit fixes some uses of strncpy that could leave the destination
buffer unterminated.

Unify version string printing2016-11-17T10:36:55+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2016-07-19T13:06:58+00:00urn:sha1:7dd42c510dc8ab10f52dcc2d20dc8af412be0744
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.

mtd-utils: Restructure the mtd-utils source.2015-11-11T22:38:40+00:00Dongsheng Yangyangds.fnst@cn.fujitsu.com2015-10-31T03:12:01+00:00urn:sha1:7d81790ced345585b1e647ca9d0f6678e7062fa4
* There is no code modification in this commit, only moving
* the files to proper place.
The user tools looks a little messy as we place almost
the all tools in the root directory of mtd-utils. To make
it more clear, I propose to introduce the following structure
for our source code.
mtd-utils/
|-- lib
|-- include
|-- misc-utils
|-- jffsX-utils
|-- nand-utils
|-- nor-utils
|-- ubi-utils
|-- ubifs-utils
`-- tests
