Daniel Golle 5c10f26c28 sysupgrade-nand: allow limiting rootfs_data by setting env variable ... Check if firmware environment variable 'rootfs_data_max' exists and is set to a numerical value greater than 0. If so, limit rootfs_data volume to that size instead of using the maximum available size. This is useful on devices with lots of flash where users may want to have eg. a volume for persistent logs and statistics or for external applications/containers. Persistence on rootfs overlay is limited by the size of memory available during the sysugprade process as that data needs to be copied to RAM while the volume is being recreated during sysupgrade. Hence it is unsuitable for keeping larger amounts of data accross upgrade which makes additional volume(s) for application data desirable.
