[SCSI] fc4: remove this and all associated drivers
This code has been slowly rotting for about eight years. It's currently impeding a few SCSI cleanups, and nobody seems to have hardware to test it any more. I talked to Dave Miller about it, and he agrees we can delete it. If anyone wants a software FC stack in future, they can retrieve this driver from git.

- ---help---
- Fibre Channel is a high speed serial protocol mainly used to
- connect large storage devices to the computer; it is compatible with
- and intended to replace SCSI.
-
- This is an experimental support for storage arrays connected to your
- computer using optical fibre cables and the "X3.269-199X Fibre
- Channel Protocol for SCSI" specification. If you want to use this,
- you need to say Y here and to "SCSI support" as well as to the
- drivers for the storage array itself and for the interface adapter
- such as SOC or SOC+. This subsystem could even serve for IP
- networking, with some code extensions.
-
- If unsure, say N.

- Serial Optical Channel is an interface card with one or two Fibre
- Optic ports, each of which can be connected to a disk array. Note
- that if you have older firmware in the card, you'll need the
- microcode from the Solaris driver to make it work.
-
- To compile this support as a module, choose M here: the module will
- be called soc.

- ---help---
- Serial Optical Channel Plus is an interface card with up to two
- Fibre Optic ports. This card supports FC Arbitrated Loop (usually
- A5000 or internal FC disks in E[3-6]000 machines through the
- Interface Board). You'll probably need the microcode from the
- Solaris driver to make it work.
-
- To compile this support as a module, choose M here: the module will

- This driver drives FC-AL disks connected through a Fibre Channel
- card using the drivers/fc4 layer (currently only SOCAL). The most

- * (that's e.g. the case with Qlogic FC cards), or leaves most of the FC
- * bookkeeping to the OS (e.g. soc, socal). Drivers for the former adapters
- * will look like normal SCSI drivers (with the exception of max_id will be
- * usually 127), the latter on the other side allows SCSI, IP over FC and other
- * protocols. This driver tree is for the latter adapters.

- * Supported hardware:
- * Tested on SOC sbus card bought with SS1000 in Linux running on SS5 and Ultra1.
- * For SOC sbus cards, you have to make sure your FCode is 1.52 or later.
- * If you have older FCode, you should try to upgrade or get SOC microcode from Sun
- * (the microcode is present in Solaris soc driver as well). In that case you need
- * to #define HAVE_SOC_UCODE and format the microcode into soc_asm.c. For the exact
- * format mail me and I will tell you. I cannot offer you the actual microcode though,
- * unless Sun confirms they don't mind.
