root mount parameters are stored in two locations: - cmdline in u-boot environemnt - machine.conf in the rescue-system initramfs If we switch to another filesystem(jffs2->ubifs), they have to change in the u-boot environment anyway, since the device still needs to boot without rescue-system. Instead of keeping u-boot-env/machine.conf in sync, make the u-boot env the sole authoritive source for those variables and ignore/retire the machine.conf variables.
