we need to account for that. Failure to do so means we can end up
waiting forever for writes we think are outstanding, but which have
already completed.
Addresses the RAIDframe part of PR#40569. Thanks to Matthias Scheler
for reporting the issue and verifying the fix.
LBA 48 work around. The first entry will watch the Seagate ST3160815AS

This avoids the RAID rebuild problems described in PR kern/40569.

is initialized to NULL before chip is identified, and if it is NULL or
ADM1027, use the less-efficient send_byte/receive_byte.
While here, don't attempt to release the i2c bus if we failed to acquire
it. This would cause a panic on a LOCKDEBUG kernel.
Thanks to Nicholas Joly for pointing out both of these bugs.
device doesn't support flushing the cache. Fixes an issue (reported
privately) where ST39120A drives are not capable of flushing the
cache, and RAIDFrame was incessantly complaining.
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

Some devices don't like to be read from (certain clock devices are, I'm
told, write-only!), while others expect to be asked only for words (or
pairs of bytes).
While here, skip a bunch of i2c addresses that can't (or at the very
least, shouldn't) have any slave devices.
This is the only use in NetBSD of the quick_read/quick_write protocol,
and it remains disabled by default. I've updated all the generic i2c
drivers to handle the quick_* protocols, but several port-specific
drivers have not been updated since I'm in no position to verify that
the changes work. Assistance from sandpoint, arm/xscale, evbarm/gumstix,
mips/alchemy, and macppc would be greatly appreciated.

NOTE: i2c controllers that provide their own i2c_exec() routine also need

cause a continous strean if interrupts with no way to clear it.
Clearing/resetting the enabled interrupt mask in the interrupt handler seems
to workaround this issue (this is what the FreeBSD driver does).
While there properly return 0 if the interrupt was not for us, and explicitely
disable JME_TMCSR in addition to TIMER1 and TIMER2.
