Hello, I stumbled upon these errors when porting to Asus M2V-MX-SE, and they are related to libgcc. Coreboot needs to be linked against libgcc when using 64bit arithmetic in 32bit code. There are a few approaches for fixing this, like: -link against libgcc (statically) -implement the needed functions ourselves (copied from libgcc) -avoid using 64bit arithmetic I'm in inclined to vote for the first approach.
