The intent was to protect the full range of ports on the board by the
barriers. But the start address was wrong. Fix it.
While here, change two other barriers to also protect the full range
(not only the nic ports), and add yet another similar barrier.
in not just used to access memory but is bassed to bus_space_xxx_n()
methods. For debugging purposes, bus_space can have additional constraints
which will be properly met by BUS_SPACE_ALIGNED_POINTER().
the "stream" busification functions.
In the architecture as the BeBox(CPU is big endian, have ISA bus),
These methods would be used where "raw" data needs to {read,write,set}
unchanged.
Add #ifndef __BUS_SPACE_NEED_STREAM_METHODS (define that on NetBSD/bebox),
if not define __BUS_SPACE_NEED_STREAM_METHODS,
define "stream" busification functions to normal busification functions.
in the ISR (from the ISA "ed" driver's generic 8390 probe routine).
Also, add a big comment describing exactly what we're checking when
probing for the dp8390 (also lifted from the ISA "ed" driver).
The RST check should help weed-out non-matches before they get to the
fairly invasive memory check.
