- Good bye SYS_PBOOT and SYS_NBOOT, hello SYS_UBOOT (unified boot)
Currently supports booting from SCSI and HP-IB disk and network
from a single boot block. Infrastructure for booting from
HP-IB tape is there, but it doesn't quite work yet.
- Add a slightly modified version of Gordon Ross's "rawfs",
which provides a filesystem-like interface to tape devices.
Still needs debugging (see above).
- Rename sys_inst.c to inst.c, so that the LIF directory entry
turns out right (used to look like SYS_SYS_I if loaded from
tape).
- Add a "netio_ask" hint to netio.c, so that a special instnetio.o
doesn't have to be compiled for SYS_INST. Defaults to using
bootparams, but if set, will prompt user for information
usually obtained from bootparams.
- General cleanup.
- New delay() function, modeled after sun3/mvme68k delay,
calibrated with a model's known cpu speed.
- Use the defined constants for machineid and ectype
when determining what kind of machine we have, rather
than their expanded equivalents, for clarity.
- Move the vector table to the data segment so that it
can be patched at run-time.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
execpt without quotes. meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).
outside of "internal i/o" space to not even have a chance at console-hood.
Fix tested by Thorsten Frueauf <frueauf@ira.uka.de>, and offered with
my sincerest apologies that the bug ever existed in the first place.
