35f31dce6e Implement consinit() here instead of using the arm32/machdep.c version. 
Use information passed from via the boot arguments to determine which
device to use as the console.
Add support for initialising the CATS ISA subsystem.
During the early bootstrapping use fcomcnattach()/fcomcndetach to enable
debug and diagnostic information to be sent to the diagnostic serial
port. This is only used during the early part of initarm() until things
have been relocated and the real console can be initialised().

18ccba3b4e Make sure ISA interrupts have been setup prior to configuring devices. 
This is not nice and a better solution is needed. Really this should be
done when the PCI-ISA bridge is discovered but it is possible that
some PCI interrupts may be routed via the ISA interrupt controller
and thus this needs setting up first.

91eeeff347 Add support for interrupts that are actually routed via an ISA interrupt 
controller.
(I'm not happy with this approach but it works so I'll use it for the
moment until I complete run-time selection of the interrupt handling based
on recognised hardware).

ec897ee047 Fix a problem reported by Michael Hitch. Basically, our libc relies on the 
non-standard way of invoking sigreturn, specifically a side-effect that I
overlooked.  Thus, longjmp's return value was getting clobbered.

Sigh, so burn trap #3 just as sigreturn.

XXX We need an SVR4-style {get,set}context(2) to avoid wasting new
XXX trap vectors in the future.

38084c6615 Note that trap #1 is compat_13_sigreturn, and give trap #3 to syscalls 
which require special handling, e.g. sigreturn on m68k.

This differs from the old sigreturn trap in that we require the syscall
number to be in register d0, just like the regular syscall entry point.
This will allow sigreturn to be versioned in the future without the need
to allocate another trap vector.

5b01d45ac4 Add a `-b #' option and logic for locating the secondary boot image via 
an absolute block address. It's cheating, as the motivation is support for
the libsa ustar tfs `filesystem' and the solution symmetrical to ufs and
cd9660 would have been to teach installboot about tfs. However, it still
would have been different as you can't mount a tfs with the kernel, and
this option gets possibly useful support for any contiguous format, even
completely raw boot images.
