gwr 8f9276c727 Move the _verify_hardware() work into machdep.c:identifycpu().
Call obio_init() after _vm_init() so we can use peek_byte() to
probe the idprom.  Be quiet in _save_symtab() when all is well.
1997-04-25 18:29:58 +00:00
gwr 477a320277 Moved bus_scan() and bus_print() here from autoconf.c
because they are now different in sun3 vs sun3x.

gwr 3619a4da3d Rename obio_alloc to obio_mapin, update *_init declarations.
Remove OBIO_P4_REG (not a fixed address, but per-device).

gwr 963c410824 Change the OBIO address probe order a little, to allow determination of
which kind of idprom and clock we have (3/80 vs 3/470 differences).
Fix a bug where obio_submatch() failed to copy some locators.
Rename obio_alloc to obio_mapin.  Add lots of comments.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will

lot of work.
