Well, MIPS bootloaders are strikingly more diverse than on ARM…

That would take a serious arch overhaul not unlike the migration to DT,
and I suspect multiple targets would break. So far, this argc == -2
stuff has been used on only two targets that I could see, so I don't
believe it belongs in head.S even with such an overhaul. That said, if
_real_ UHI spec compliance gets in, the SoC-specific stuff could just be
dropped. In the meantime, I propose this patch with the changes
previously suggested.
