Paul Gortmaker bb8187d35f MCA: delete all remaining traces of microchannel bus support. 
Hardware with MCA bus is limited to 386 and 486 class machines
that are now 20+ years old and typically with less than 32MB
of memory.  A quick search on the internet, and you see that
even the MCA hobbyist/enthusiast community has lost interest
in the early 2000 era and never really even moved ahead from
the 2.4 kernels to the 2.6 series.

This deletes anything remaining related to CONFIG_MCA from core
kernel code and from the x86 architecture.  There is no point in
carrying this any further into the future.

One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

CREDITS

	This work was made possible by 

Red Hat Software
	Funding for the Building #3 part of the project

Symbios Logic (Now LSI)
	Host adapters, hints, known to work platforms when I hit
	compatibility problems

BoxHill Corporation

STATUS:

o	The core setup works within limits.
o	The scsi layer seems to almost work. 
           I'm still chasing down the hang bug.
o	The block OSM is mostly functional
o	LAN OSM works with FDDI and Ethernet cards.

TO DO:

General:
o	Provide hidden address space if asked
o	Long term message flow control
o	PCI IOP's without interrupts are not supported yet
o	Push FAIL handling into the core
o	DDM control interfaces for module load etc
o       Add I2O 2.0 support (Deffered to 2.5 kernel)

Block:
o	Multiple major numbers
o	Read ahead and cache handling stuff. Talk to Ingo and people
o	Power management
o	Finish Media changers

SCSI:
o	Find the right way to associate drives/luns/busses

Lan:	
o	Performance tuning
o	Test Fibre Channel code

Tape:
o	Anyone seen anything implementing this ?
           (D.S: Will attempt to do so if spare cycles permit)
