Add CDIOCREADSUBCHANNEL_BUF and CDIOREADTOCENTRIES_BUF which are like the
existing ioctls withoutthe _BUF, except that the data area immediately
follows the control structure (and is fixed length).
Modify scsipi/cd.c so that it only ever has one 'struct cd_formatted_toc'
allocated on the stack (maybe this info ought to be in the softc)
structure since even one 800 byte on-stack buffer isn't overly friendly.
cdplay(1) still seems able to read the track-list of an ATAPI cd.

won't error out but will return garbage data. Implemented by generalising
the odd-check for PIO selection to check for 4 byte alignment in offset and
size.
Note that this check could be relaxed by checking if the ATAPI/ide bus
width is 16 for the device but its unknown to me if that information is
available here.
the command block) - but instead of fixing this, we can now revert it
completley: the real fix has been applied to ../ic/wdc.c in rev. 1.244,
removing the alignement constraints.
From the PR:
Since struct scsipi_read_discinfo_data is an odd number of bytes long
(35 bytes), ti ends up being unaligned. wdc_datain_pio() uses
bus_space_read_multi_4() to read the response from the drive, and
since ti is unaligned, it causes an unaligned access fault.
Add __aligned__(4) to all the structures.
the d_typename field of the default disklabel is initialized with
text from the SCSI inquiry, so that one gets at least a vague idea which
disk he is dealing with
Use Request Sense only if Read Capacity succeeded and did not return
valid block size.

Fix the easier part of NetBSD PR kern/26537.
(The harder part is the device hangs on large (>= 8KB) transfer.
Possibly umass BBB problem?)
Remove scsipi_size() and scsipi_validate_secsize() from scsipi_base.c
and add their functions to sd.c since they are used only by sd.c.
Use SCSI term `block' instead of `sector' where applicable.

- bounds_check_with_label() has been fixed, so put the correct partition

fatal.. A `long write in progress' is a retry again later command that is
issued when a device returns immediately after a write request but needs
some time before it can handle read requests.
simply return zero for logical block size. In either case, use the sector
length reported by READ_CAPACITY instead of defaulting to 512 bytes.
This partially addresses the problems reported in PR port-i386/34707 and
PR kern/34737. Namely the incorrectly reported drive geometry and the
'hanging' issue.
However, since the device in question reports 2048-byte physical sectors
it will remain unusable until DEV_BSIZE is banished.
structures can thus be misaligned for DMA when declared on stack.
The current atapi code accepts the misaligned dma's only screw's them up.
This small patch disables DMA for the rare transactions that are
misaligned. Note that all bulk-transfers are aligned due to page sizes.

pseudo array in the structure. The scsi command issued used
sizeof(scsipi_read_discinfo_data) but included thus the last byte that
wasn't going to be inspected anyway. Using the constant
READ_DISCINFO_BIGSIZE fixes the bug.
Even though SCSI adapters *should* accept odd lengths, the Sun U10
(sparc64's) crashes in bus_space_read_multi_stream_2(). That explains the
crash.
NOTE: somewhere in NetBSD/sparc64's atapibus support there is the
assumption on the even size; this needs to be fixed! (Hi Sparc64 portmaster
:-) )
The PIOBM is used by only one driver (will be added later,
stay tuned) and intruduce an attribute "ata_piobm" so that
it will be conditionally compiled in.
The "ata_dma" (busmastering transfer using ATA DMA mode) and
"ata_udma" (busmastering transfer using ATA Ultra DMA mode)
attributes are also added for consistency, but unused for now.
