bus_space_map for PCI memory.
The mapping of system devices and I/O space has been shuffled to place them
at the top of memory leaving a larger contiguous chunk between the kernel
itself and the I/O mappings for the kernel VM area. This allows support
for kernel VM areas > 48MB.
The 144MB fixed mapping of early PCI memory space has been removed and a
new version of the bus_space_map() function has been implemented to map
PCI memory into the kernel VM area as required rather than using the fixed
mapping.
A mapping of the first 1MB of PCI memory is maintained for ISA memory
accesses and accesses to the VGA memory.
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().
