In directory pain.lcs.mit.edu:/b/tmp/cvs-serv27930

Modified Files:
        ncr.c ncr_reg.h 
Log Message:
Move INT32, U_INT32, TIMEOUT definitions to ncr_reg.h, and add definitions
    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.
