From 730148bc94411f13a0171204e872b0760fbde185 Mon Sep 17 00:00:00 2001 From: Brandon Maier Date: Mon, 12 Dec 2022 12:01:58 -0600 Subject: mtd-utils: Add new syntax to get devices by name 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.
