Merge branch 'delete-8390-EISA' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Paul Gortmaker says:

====================
I'd like to propose that we get rid of these old 8390 EISA drivers.
Of the five deleted here, I wrote four -- and while that doesn't give
me any authority for deletion above anyone else, it does at least
allow me to comment on the absolute absence of anyone reaching
out to the driver author for assistance in the last dozen years.

Eventually we'll probably get rid of EISA bus support, since in
x86, the hardware is close to 20 years old and already too resource
constrained to be useful today.  However there might still be
a few DEC Alpha enthusiasts with old EISA machines kept alive,
and so I expect we'll have to wait a bit longer to get unanimous
agreement to proceed with the full EISA removal (although I'd
love to be proven wrong on that).

Most of the DEC Alpha machines shipped in a PCI configuration, and
even the few that were EISA had DEC tulip based ethernet and no
reason to be needing the inferior 8390 technology.  So the interest
here for any possible DEC enthusiasts with EISA boxes about these
old 8390 drivers should be nil.

These really were rare cards -- in fact the smc-ultra32 is the only
one that I'd ever seen in person.  Even back in the mid 90's when
the drivers were written, I would guess that the user base was less
than 10 people across all of them.

The following patch was created with --irreversible-delete for
ease of review (it skips showing the content of files that are
deleted); however the complete patch can be pulled as per below.

-/* 	smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
-
-Sources:
-
-	This driver is based on (cloned from) the ISA SMC Ultra driver
-	written by Donald Becker. Modifications to support the EISA
-	version of the card by Paul Gortmaker and Leonard N. Zubkoff.
-
-	This software may be used and distributed according to the terms
-	of the GNU General Public License, incorporated herein by reference.
-
-Theory of Operation:
-
-	The SMC Ultra32C card uses the SMC 83c790 chip which is also
-	found on the ISA SMC Ultra cards. It has a shared memory mode of
-	operation that makes it similar to the ISA version of the card.
-	The main difference is that the EISA card has 32KB of RAM, but
-	only an 8KB window into that memory. The EISA card also can be
-	set for a bus-mastering mode of operation via the ECU, but that
-	is not (and probably will never be) supported by this driver.
-	The ECU should be run to enable shared memory and to disable the
-	bus-mastering feature for use with linux.
-
-	By programming the 8390 to use only 8KB RAM, the modifications
-	to the ISA driver can be limited to the probe and initialization
-	code. This allows easy integration of EISA support into the ISA
-	driver. However, the driver development kit from SMC provided the
-	register information for sliding the 8KB window, and hence the 8390
-	is programmed to use the full 32KB RAM.
-
-	Unfortunately this required code changes outside the probe/init
-	routines, and thus we decided to separate the EISA driver from
-	the ISA one. In this way, ISA users don't end up with a larger
-	driver due to the EISA code, and EISA users don't end up with a
-	larger driver due to the ISA EtherEZ PIO code. The driver is
-	similar to the 3c503/16 driver, in that the window must be set
-	back to the 1st 8KB of space for access to the two 8390 Tx slots.
-
-	In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
-	be a limiting factor, since the EISA bus could get packets off
-	the card fast enough, but having the use of lots of RAM as Rx
-	space is extra insurance if interrupt latencies become excessive.
