Among other improvements, this patch series fixes a data corruption bug

A system bus error during a PDMA send operation can result in bytes being

Add support for Apple's custom "SCSI DMA" chip. This patch doesn't make

Some targets introduce delays when handshaking the response to certain
commands. For example, a disk may send a 96-byte response to an INQUIRY
command (or a 24-byte response to a MODE SENSE command) too slowly.
Apparently the first 12 or 14 bytes are handshaked okay but then the

This reverts commit 4822827a69d7cd3bc5a07b7637484ebd2cf88db6.
The purpose of that commit was to suppress a timeout warning message
which appeared to be caused by target latency. But suppressing the warning
is undesirable as the warning may indicate a messed up transfer count.

A PDMA error is handled in the core driver by setting the device's
'borken' flag and aborting the command. Unfortunately, do_abort() is not
dependable. Perform a SCSI bus reset instead, to make sure that the
command fails and gets retried.

A system bus error during a PDMA transfer can mess up the calculation of
the transfer residual (the PDMA handshaking hardware lacks a byte
counter). This results in data corruption.
The algorithm in this patch anticipates a bus error by starting each
transfer with a MOVE.B instruction. If a bus er
The reselection interrupt gets disabled during selection and must be
