From: Felix Fietkau <n...@openwrt.org> mtd: block2mtd: wait for device enumeration, add name support
Currently, a block MTD device is not presented timely on boot time, in order to start mounting the filesystems, causing the system to not boot or panic because of lack of rootfs. This patch ensures that block2mtd is presented at the right time, so the filesystems can be mounted on boot time. This issue was seen on BCM2835 (Raspberry Pi) systems when mounting JFFS2 block2mtd filesystems. This patchset also adds a MTD device name and a timeout option to the driver and deprecates PAGE_MASK when calculating the device size.
