mtd: block2mtd: add support for an optional custom MTD label
This patch adds support for an optional MTD label for mtd2block emulated
MTD devices. Useful when, e.g., testing device images using Qemu.
The following line in /etc/fstab can then be used to mount a file system
regardless if running on an embedded system, or emulated with block2mtd:
mtd:Config /mnt jffs2 noatime,nodiratime 0 0
Kernel command line syntax in the emulated case:
block2mtd.block2mtd=/dev/sda,,Config
Notice the ',,' it is the optional erase_size, which like before this
patch, defaults to PAGE_SIZE when omitted. Hence the strlen() check.
