Hi!
> You need either to use cache as RAM

On those very old processors and chipsets it's rather unlikely that you'll get cache as RAM working, since those are typically missing some rather essential functionality for that; mostly that they don't have MTRRs.
Using romcc would probably be an option, but romcc romstage was dropped a few years ago, so that's not useful for porting the device to a current coreboot version.
Using an old (pre romcc-romstage removal) coreboot version or even linuxbios (not to be confused with linuxboot) is probably your best bet here.
