From 74a0f963ed364f90b937fc24f06573f5512c612c Mon Sep 17 00:00:00 2001 From: Danomi Manchego Date: Tue, 28 Jan 2014 23:54:00 -0500 Subject: [PATCH] fs/ubi: add option to use custom ubinize config file By default, the UBI FS target creates a ubinize configuration file on-the-fly, for a single volume. Add an option to specify a custom config file. E.g., one might want to deploy a system with a volume for the built ubifs image, a volume for a future upgrade image, and a volume for user data.
