Warner Losh	e0ba3d7e56	Massive overhaul of exca to help with the isa efforts: ... o chip_name arrays ifdef'd out. o use the OLDCARD-like get/put functions so we can support differnt types of mappings. o Write the beggings of is this a valid exca device and introduce more chipset support. # this is partially a wip, but also needed because some other cahnges I've # made require some of these changes.	2003-02-14 06:21:18 +00:00
Warner Losh	6dfd31d460	MFp4: ... o Protect .h against multiple includes. o eliminate the pointers to the read/write routines. The bus_space_read routines can cope since we have the offset field. o Print a warning if the requested map address is > 16M and your chipset doesn't support the extended ExCA registers.	2002-07-26 08:01:08 +00:00
Warner Losh	c3ee5891b9	First draft of common code between pccbb and pcic drivers for talking ... to ExCA register sets. These registers exist in both ISA and PCI devices in a couple different ways, and this will provide a common base for future building. This code is a rehash of the pccbb 16-bit code, which was a rehash of the pcic code, which was a rehash of the netbsd i82365 code. More hashing to come.	2002-01-29 06:48:38 +00:00
