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.

config SCSI_IBMMCA

	---help---

	  This is support for the IBM SCSI adapter found in many of the PS/2

	  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.

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.
