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.

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.
