support for new -v, -q boot flags (or bootverbose/bootquiet) is
now in tree, as discussed previously on tech-kern. Flag -v switches on
"verbose" boot (extra messages printed). This is primarily usable
to be able to get extra debugging information from kernel, but not print it
for "standard" boot. Flag -q switches on "quiet" boot - in theory some
less usable standard messages not printed. The latter is not used
by any driver at this moment, so it does not have any effect.
Couple of drivers already check for verbose boot and react accordingly.
Commonly, those drivers previously printed the extra messages ifdef
DEBUG or unconditionally, so expect a change here. ahc, ncr and ti
drivers are affected.
In order to use new boot flags, you typically need to update your boot blocks,
though it's not needed for ports which parse boot flags in kernel instead
of in boot blocks (like alpha).
The changes were tested on i386 and to limited extend (compile of
changed files) also on couple of m68k-base platforms. Though the
changes are not complicated, they may cause unpredicted problems
on other platforms or may not be compilable. This is unfortunate,
but I don't have access to more platforms at this time. If you
encounter any error, please let know about it via send-pr or email
to me, so that it gets fixed.
