for U_INT8, INT16, U_INT16 definitions. Convert structs and
definitions in ncr_reg.h (e.g. ncrcmd, the chip register layout, etc.)
to use these definitions.
Add INB_OFF, INL_OFF, and OUTL_OFF macros to access specified offsets into
I/O or memory space. Convert register dumps (etc.), and cache snoop
test to use these new macros, so that nothing accesses the device
I/O or memory space directly. (Register dumps now come from I/O space
if NCR_IOMAPPED. They used to bogusly use memory space.)
Add a new relocation type for script entries, RELOC_KVAR. Allow scripts
access to mono_time.tv_sec, mono_time, and ncr_cache via this
mechanism, and convert scripts to use it. An ncrcmd is only 32 bits
wide, and KVAs may be > 32 bits wide (e.g. on Alpha), leading to
linker problems. This is a safer way to do this anyway; relocation is
more deterministic this way, and doesn't rely on KVAs not looking like
other relocation types.
Panic if an unmatched relocation other than 'zero' is specified. That's
now a script bug. (This used to be used to convert KVAs of kernel
variables referenced in the script to PCI bus physical addresses,
and that is now handled by RELOC_KVAR relocations.)
Figure out and print the model of chip.

multiport cards no longer need 'flags 1', because the "don't set IEN"
requirement is communicated by the commulti_attach_args. com.c no longer
recognizes 'flags 1' at all.
substantial reworking of the multi-port drivers, as they need to frob
bits in the io-port spaces of their children. As a result, the
commulti->com attachment interface is substantially more complex.
(This may be fixable in the future by making some of the code common,
but as long as io-port allocation checking is planned, it's necessary.)
exist in the source tree or defined(EXPORTABLE_SYSTEM). This works around
the fact that telnet(1) will break during a "make build" because the
exportable libtelnet will get installed while the domestic telnet(1) binary
is still in place. (XXX)
partition, add the MBR partitions to the default (faked-up)
disklabel used by NetBSD if it can't find a real one. If the
type of the MBR partition is one of the common DOS ones, mark the
partition as having an MSDOS filesystem.
