scsi: delete the MCA specific drivers and driver code



The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.

This commit removes the MCA specific SCSI drivers, and the
MCA specific portions of code in dual role ISA/MCA drivers.
Also, the MCA specific SCSI documentation is removed.

This is support for Future Domain MCS 600/700 MCA SCSI adapters.
Some PS/2 computers are equipped with IBM Fast SCSI Adapter/A which
is identical to the MCS 700 and hence also supported by this driver.
This driver also supports the Reply SB16/SCSI card (the SCSI part).

config SCSI_IBMMCA
tristate "IBMMCA SCSI support"

---help---
This is support for the IBM SCSI adapter found in many of the PS/2
series computers. These machines have an MCA bus, so you need to
answer Y to "MCA support" as well and read
<file:Documentation/mca.txt>.
If the adapter isn't found during boot (a common problem for models
56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
option, where <pun> is the id of the SCSI subsystem (usually 7, but
if that doesn't work check your reference diskette). Owners of
model 95 with a LED-matrix-display can in addition activate some
activity info like under OS/2, but more informative, by setting
'ibmmcascsi=display' as an additional kernel parameter. Try "man
bootparam" or see the documentation of your boot loader about how to
pass options to the kernel.
To compile this driver as a module, choose M here: the
module will be called ibmmca.
config IBMMCA_SCSI_ORDER_STANDARD
bool "Standard SCSI-order"
depends on SCSI_IBMMCA
---help---
In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
are assigned to the drive letters, starting with the lowest SCSI-id
(physical number -- pun) to be drive C:, as seen from DOS and
similar operating systems. When looking into papers describing the
ANSI-SCSI-standard, this assignment of drives appears to be wrong.
The SCSI-standard follows a hardware-hierarchy which says that id 7
has the highest priority and id 0 the lowest. Therefore, the host
adapters are still today everywhere placed as SCSI-id 7 by default.
In the SCSI-standard, the drive letters express the priority of the
disk. C: should be the hard disk, or a partition on it, with the
highest priority. This must therefore be the disk with the highest
SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
original definition of the SCSI-standard as also industrial- and
process-control-machines, like VME-CPUs running under realtime-OSes
(e.g. LynxOS, OS9) do.
If you like to run Linux on your MCA-machine with the same
assignment of hard disks as seen from e.g. DOS or OS/2 on your
machine, which is in addition conformant to the SCSI-standard, you
must say Y here. This is also necessary for MCA-Linux users who want
to keep downward compatibility to older releases of the
IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
June 1997).
If you like to have the lowest SCSI-id assigned as drive C:, as
modern SCSI-BIOSes do, which does not conform to the standard, but
is widespread and common in the PC-world of today, you must say N
here. If unsure, say Y.
config IBMMCA_SCSI_DEV_RESET
bool "Reset SCSI-devices at boottime"
depends on SCSI_IBMMCA
---help---
By default, SCSI-devices are reset when the machine is powered on.
However, some devices exist, like special-control-devices,
SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
not reset when switched on. If you say Y here, each device connected
to your SCSI-bus will be issued a reset-command after it has been
probed, while the kernel is booting. This may cause problems with
more modern devices, like hard disks, which do not appreciate these
reset commands, and can cause your system to hang. So say Y only if
you know that one of your older devices needs it; N is the safe
answer.
