Update of /cvsroot/src/sys/arch/amiga/amiga
In directory netbsd1:/var/slash-tmp/cvs-serv5348/amiga

Modified Files:
        locore.s 
Log Message:
Add option BB060STUPIDROM, which makes the early kernel startup probe for
an 68060/68LC060, possibly switching on the 68060 FPU, instead of trusting
the value passed from the ROM OS to us by the bootblock.

Most 68060 boards, unlike the DraCo (which seems to have heavily patched OS 
ROMs) don't set the AMIGA_68060 flag; instead, upon detecting an 68060, its
FPU is disabled to make the ROM scheduler work, and at a much later time (at
least, later than bootblock booting time), the "68060.library" installs the
Motorola 68060 software support, patches the scheduler for the 68060 FPU, and
re-enables the FPU.

Maybe this will be fixed one day, if Amiga International sells upgraded OS
ROMs which know about the 68060. Until then, and for legacy machines, this 
kludge is needed if we want to boot a non-DraCo 68060.

Btw, thats why this is NOT in std.amiga, but in GENERIC; the DRACO
configuration doesn't need it (and I still plan to make std.draco go away).
