Subject: Makefile: Generate config files
X-Git-Tag: v1.0b1~26
X-Git-Url: https://git.htl-mechatronik.at/public/?a=commitdiff_plain;h=5159dffcaccabb4fe8b04e1854e944132a31aa78;p=sx%2Fsimavr.git

Makefile: Generate config files

The Makefile now tries to detect the cores that can
be built using the current avr-gcc install. This allows
simavr to be built with older toolchain that don't have
the latest cores. Like arduidiot.

It also allows generation of an automated core list for
simavr so the run_avr and others don't have to have an
explicit list of cores. They are now autodetected.
