A buildroot tree containing a gcc-4.2.4 patch can be found here: git://github.com/img-meta/metag-buildroot.git metag-core Use meta2_defconfig There's a known issue with all/random config builds with this toolchain which results in internal compiler errors triggered by the inline asm in arch/metag/include/asm/io.h when used by certain drivers, so I need to update the patch to the latest before these will go away. The other main issue with all/random config builds for Meta is a few missing !METAG dependencies on legacy PC peripherals like SERIO_I8042, which I believe you've already come across for Arc. Please read this thread before attempting to fix them: https://lkml.kernel.org/r/201211161520.03974.arnd-r2nGTMty4D4@public.gmane.org I haven't got around to fixing this properly myself, but it would be a worthwhile improvement if you felt inclined to do so.
