Jake Burkholder	6bfa8a2ef2	Split this into bus specific front end(s), so that it can be used by ppc. ... This abstracts out all the differences I could see between the netbsd sparc64 and macppc zs drivers. In particular the offsets of the csr and data registers are different, so we use a separate bus handle for each and use bus_space_subregion to add the bus specific offsets.

Jake Burkholder	75db2b5e27	Add a driver for the Zilog 8530 dual uart found in Ultra 1s and Ultra 2s. ... With a 1 byte transmit fifo, 3 byte receive fifo, and wierd multiplexed I/O designed for a Z80 cpu, this chip redefines suckage. Based on the openbsd and netbsd drivers. Only really works as a console, modem support is not complete since I can't test it.	2003-01-01 19:49:30 +00:00
