e6548e54bd Enable interrupts *after* reading the fault address and status. This is 
necessary because some interrupt handlers may cause additional faults (e.g.
through R/M emulation) and thereby trash the previous fault state.
From Richard Earnshaw.

Now that we support various models, the old constant-loop delay routine

22de25977b Argh, removed last ELF induced problem. We used to have syscall: in locore.s 
and _C_LABEL(syscall) in trap.c. In ELF they are the same. Change the label
in locore.s to be _C_LABEL(_syscall).
While I am there, move the register save and restoral code used in the
*sigcode trampolines into two macros and use them instead of copying 100
lines of assembly each time.
Now everything ELF works.

952f511570 Use -n for ELF. Using -N might work, but produces only one section. 
No flags will not work, because it will produce a kernel loaded at 0xf0000000.
This is because the bfd ELF pagesize (in elf32-sparc.c) is 0x10000. Since
we need to load at 0xf0004000, we use -n.

fc645b996a - Always config_found() PCI busses, so we know if present PCI busses 
aren't configured.

the bus.

654b0fff46 - Completely rewrite how bus space tags for PCI space are set up. Instead 
of hard-coding them, decode the "ranges" property of the PCI bus node in
OpenFirmware.
- Do a little cleanup, and share some more code between the Bandit/Chaos
and MPC106.

XXX The bus_space(9) implementation for macppc really needs to be
rewritten.

a4adbf2f86 Move initialization of the iomem extent struct from mac68k_set_io_offset() 
to mac68k_init(), so that we're through frobbing the MMU in special ways
by the time we get there.  While it doesn't actually cause a problem with
the current structure of our initialization code, it probably would have
in the future.
