[coreboot] On loongson CPU or MIPS ARCH

[ron minnich]

let's take this one step at a time.

First off, we're going to need to work out names. Since loongson
requires patches, does that mean it is more or less than a base mips?

So, what do we use as names?

Let's start with the arch/ and cpu/
src/arch/? mips? Is it a true mips?

src/cpu/loongson/? what name here?
