Drivers that define PSEUDO_DMA also define NCR5380_dma_xfer_len.
The core driver must call NCR5380_dma_xfer_len which means
FLAG_NO_PSEUDO_DMA can be eradicated from the core driver.
dmx3191d doesn't define PSEUDO_DMA and has no use for FLAG_NO_PSEUDO_DMA,
so remove it there also.

The driver has a limit of eight LUs because of the byte-sized bitfield
that is used for busy flags. That means the maximum LUN is 7. The default

This patch series has more macro elimination and some tweaks to the
DMA hooks so that all the wrapper drivers can share the same core
DMA algorithm. This resolves the major discrepancies between the two
core drivers, which relate to code conditional on the REAL_DMA and
PSEUDO_DMA macros.

The benefit of limiting can_queue to 1 is that atari_scsi shares the
ST DMA chip more fairly with other drivers (e.g. falcon-ide).
Unfortunately, this can limit SCSI bus utilization. On systems without
IDE, atari_scsi should issue SCSI commands whenever it can arbitrate for
the bus. Make that poss
For the NCR5380.c core driver, these macros are never used.
If REAL_DMA were to be defined, compilation would fail.
For the atari_NCR5380.c core driver, REAL_DMA is always defined.
Hence these macros are pointless.

Standardize the DMA setup hooks so that the DMA implementation in
atari_NCR5380.c can be reconciled with pseudo DMA implementation in
NCR5380.c.
Calls to NCR5380_dma_recv_setup() and NCR5380_dma_send_setup() return
a negative value on failure, zero on PDMA transfer success and a positive

Those wrapper drivers which use DMA define the REAL_DMA macro and
those which use pseudo DMA define PSEUDO_DMA. These macros need to be
removed for a number of reasons, not least of which is to have drivers

The io_recovery_delay macro is intended to insert a microsecond delay

NCR5380_dma_xfer_len() evaluate to zero. That allows PDMA to be easily
disabled at run-time and so the PSEUDO_DMA macro is no longer needed.
Also remove the spin counters used for debugging pseudo DMA drivers.

The only chip that needs the workarounds enabled is an early NMOS
device. That means that the common case is to disable them.
Unfortunately the sense of the flag is such that it has to be set
for the common case.
Rename the flag so that zero can be used to mean "no errata workarounds
needed". Thi
This change brings a number of improvements: fewer macros, better test
coverage, simpler code and sane Kconfig options. The downside is a small
chance of incompatibility (which seems unavoidable).
