Don't try to read disklabel to check FS_RAID on floppy boot since
reopening floppy could cause Data Access Exception later.
Fixes PR port-sparc/42186, ok'ed by mrg@.
Use /dev/fd0a rather than /dev/rfd0a to read instfs.tgz image from floppy.
It looks newer (appearred after 1.6) gzip tries to read less than DEV_BSIZE
(to check header?) so we can't use raw device directly.
(note sparc bootfs ramdisk doesn't have dd(1))
Workaround for PR port-sparc/42193, and would also fix PR install/28734.
Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
A comment in the macro says AUXIO4M_FTC bit is auto-clear,
but my two SS20s (including compatible) with 150MHz hyperSPARCs
get data_overrun without it, and no bad side effect on SS5
(works with and without this change).
Closes PR port-sparc/42516, which is the last one of a bunch of
floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
http://mail-index.NetBSD.org/port-sparc/2009/12/20/msg000484.html
for details.
