You're probably right.  I'll send you ARCDIAG off the list.

Probably not.  That's normal. "ARC Multiboot Version 174 (SGI Version 2.6)"

Unfortunately, the MCT ADR ASIC doesn't show up in the device tree.  The only
way to know which ASIC you have is to pop the hood.  But I'm willing to bet
you have an LSI Logic-made R4230.
