First part of M68060 and DraCo support. * for the M68060 part: store buffer and branch target cache aren't enabled yet (this needs cleanup of lots of locore.s code which is a maze of little passages, all a little different) (and it wasn't yet tested in an accellerated Amiga, only in the DraCo). I've included a workaround for 2 of the CPU bugs in chips with Masks 1F43G and earlier, but didn't bother to deal with the can of worms in the [0-3]D11W chips. Be sure to get "68060 rev. 1" or more reported at kernel startup time, or at least mention it (or the mask revision, if available) when reporting problems. * for the DraCo: only machines with a CIA timer. I assigned machine id 32000+nn (0x7Dnn), where n is the machine readable Quicklogic custom chip revision (also printed at boot time). "Guaranteed to work" up to rev. 3, newer DraCo's aren't guaranteed to have any CIA (we don't have a driver for the new timer yet). Supported are: - MF-II keyboards on the native interface and A3000 keyboards via the CIA. - builtin SCSI interface (yet another instance of siop) - CIA timer. - Zorro II devices which don't do DMA (don't get mapped to Zorro II address space in the DraCo) - "local bus" devices which are autoconfigured by the boot rom (should be all); only an Altais driver is there (looks like a Retina Z3) Not yet supported are: - native timer of newer machines. - Real Time Clock. - serial, parallel + floppy on the SuperIO chip (that is also: no mouse) XXX You need an enhanced boot loader, which will committed in a few days. XXX std.draco should and will go away.

I've included a workaround for 2 of the CPU bugs in chips with Masks 1F43G and earlier, but didn't bother to deal with the can of worms in the [0-3]D11W chips. Be sure to get "68060 rev. 1" or more reported at kernel startup time, or at least mention it (or the mask revision, if available) when reporting problems. * for the DraCo: only machines with a CIA timer. I assigned machine id 32000+nn (0x7Dnn), where n is the machine readable Quicklogic custom chip revision (also printed at boot time). "Guaranteed to work" up to rev. 3, newer DraCo's aren't guaranteed to have any CIA (we don't have a driver for the new timer yet). Supported are: - MF-II keyboards on the native interface and A3000 keyboards via the CIA. - builtin SCSI interface (yet another instance of siop) - CIA timer. - Zorro II devices which don't do DMA (don't get mapped to Zorro II address space in the DraCo) - "local bus" devices which are autoconfigured by the boot rom (should be all); only an Altais driver is there (looks like a Retina Z3) Not yet supported are: - native timer of newer machines. - Real Time Clock. - serial, parallel + floppy on the SuperIO chip (that is also: no mouse) XXX You need an enhanced boot loader, which will committed in a few days. XXX std.draco should and will go away.
