But that would be different from how we handle all other targets currently... IMHO we shoud go into a different direction instead, e.g. by adding a "--kconfig-dir" switch to the configure script. If it has not been specified, the configs will be read from default-configs/ (or maybe we should then rename it to configs/default/). But if the switch has been specified with a directory as parameter, the config files will be read from that directory instead. We could then have folders like: - configs/default (current default-configs) - configs/no-tcg (all machines that work without tcg) - configs/lean-kvm (for "nemu"-style minimalistic settings) etc. What do you think?
