mtd-utils: Add new syntax to get devices by name

2023-05-30T09:12:12+00:00

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.

mtd-utils: common.c: convert to integer arithmetic

2018-01-30T08:24:19+00:00

We use floating point just to print out KiB, MiB, GiB. Avoid that to be klibc friendly. Fixes compilation for aarch64 against klibc: error: '-mgeneral-regs-only' is incompatible with floating-point argument | printf("%s%.1f GiB", p, (double)bytes / (1024 * 1024 * 1024)); etc. Signed-off-by: Andrea Adami Signed-off-by: David Oberhollenzer

Merge rest of ubiutils-common into libmtd common

2016-11-17T10:36:56+00:00

This patch moves the remaining 3 functions from ubiutils-common.{c,h} into libmtd common.{c,h}. The functions are only generic utility functions that other mtd-utils programs may also find usefull and every program that uses libubi links against libmtd anyway so there is no real reason for keeping around a seperate ubiutils-common with only generic helper functions.
