I don't think it's a problem for getty, but still worth noting
somewhere, this will replace '115200' (without the quotes) by say
"9600" (with the quotes) because the quotes are present in
system/Config.in (maybe they could be removed ? There's no type for
that sort of things in Kconfig as far as I know (which is not much) ?
Other than that, it's fine by me.
