Subject: [PATCH 1/1] remove cpqarray from mainline kernel
From: Mike Miller <mike.miller@...com>
cpqarray hasn't been used in over 12 years. It's doubtful that anyone still
uses the board. It's time the driver was removed from the mainline kernel.
The only updates these days are minor and mostly done by people outside of HP.

-This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
-
-Supported Cards:
-----------------
-
-This driver is known to work with the following cards:
-
- * SMART (EISA)
- * SMART-2/E (EISA)
- * SMART-2/P
- * SMART-2DH
- * SMART-2SL
- * SMART-221
- * SMART-3100ES
- * SMART-3200
- * Integrated Smart Array Controller
- * SA 4200
- * SA 4250ES
- * SA 431
- * RAID LC2 Controller
-
-It should also work with some really old Disk array adapters, but I am
-unable to test against these cards:
-
- * IDA
- * IDA-2
- * IAES
-
-
-EISA Controllers:
------------------
-
-If you want to use an EISA controller you'll have to supply some
-modprobe/lilo parameters. If the driver is compiled into the kernel, must
-give it the controller's IO port address at boot time (it is not
-necessary to specify the IRQ). For example, if you had two SMART-2/E
-controllers, in EISA slots 1 and 2 you'd give it a boot argument like
-this:
-
- smart2=0x1000,0x2000
-
-If you were loading the driver as a module, you'd give load it like this:
-
- modprobe cpqarray eisa=0x1000,0x2000
-
-You can use EISA and PCI adapters at the same time.
-
-
-Device Naming:
---------------
-
-You need some entries in /dev for the ida device. MAKEDEV in the /dev
-directory can make device nodes for you automatically. The device setup is
-as follows:
-
-Major numbers:
- 72 ida0
- 73 ida1
- 74 ida2
- 75 ida3
- 76 ida4
- 77 ida5
- 78 ida6
- 79 ida7
-
-Minor numbers:
- b7 b6 b5 b4 b3 b2 b1 b0
- |----+----| |----+----|
- | |
- | +-------- Partition ID (0=wholedev, 1-15 partition)
- |
- +-------------------- Logical Volume number
-
-The device naming scheme is:
-/dev/ida/c0d0 Controller 0, disk 0, whole device
-/dev/ida/c0d0p1 Controller 0, disk 0, partition 1
-/dev/ida/c0d0p2 Controller 0, disk 0, partition 2
-/dev/ida/c0d0p3 Controller 0, disk 0, partition 3
-
-/dev/ida/c1d1 Controller 1, disk 1, whole device
-/dev/ida/c1d1p1 Controller 1, disk 1, partition 1
-/dev/ida/c1d1p2 Controller 1, disk 1, partition 2
-/dev/ida/c1d1p3 Controller 1, disk 1, partition 3
