is 1a41d54c27 Yet some more cleanup for missing prototypes, if DRACO is supported. 1996-05-19 19:03:01 +00:00
is f6ab1073c8 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.
