WIP check-in. Things work now, but I'm still working on the code.
Converted address maps to tokens. Changed the address_map structure
to house global map-wide information and hung a list of entries off
of it corresponding to each address range. Introduced new functions
address_map_alloc() and address_map_free() to build/destroy these
structures. Updated all code as necessary.
Fixed several instances of porttagtohandler*() in the address maps.
Drivers should use AM_READ_PORT() macros instead.
ADDRESS_MAP_EXTERN() now is required to specify the number of
databits, just like ADDRESS_MAP_START.
Removed ADDRESS_MAP_FLAGS() grossness. There are now three new macros
which replace its former usage. ADDRESS_MAP_GLOBAL_MASK(mask)
specifies a global address-space-wide mask on all addresses. Useful
for cases where one or more address lines simply are not used at
all. And ADDRESS_MAP_UNMAP_LOW/HIGH specifies the behavior of
unmapped reads (do they come back as 0 or ~0).
Changed internal memory mapping behavior to keep only a single
address map and store the byte-adjusted values next in the address
map entries rather than maintaining two separate maps. Many other
small internal changes/cleanups.
