"the cmdline parser"? AFAIK there is no cmdline parser for the kernel
command line(?) in barebox. And if it were, the latter is ' '-separated
while the mount options are ','-separated. This could be abstracted, but
I think for now and until we need a linux kernel commandline parser it's
fine to hardcode ',' and let it live in fs/.
Best regards
Uwe
