Aaron Giles ddfc0c3259 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.		2008-03-09 21:59:57 +00:00
