Hi,
the attached patch adds crossgcc, our coreboot cross toolchain builder to coreboot v2. It's a simple script to build xxx-elf toolchains that are known-good for coreboot.
Best regards, Stefan

This adds a simple script to build a default toolchain for coreboot
compilation, to be independent of broken or missing OS/distribution
tool chains.
