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.

es3210.c
Linux driver for Racal-Interlan ES3210 EISA Network Adapter
Copyright (C) 1996, Paul Gortmaker.
This software may be used and distributed according to the terms
of the GNU General Public License, incorporated herein by reference.
Information and Code Sources:
1) The existing myriad of Linux 8390 drivers written by Donald Becker.
2) Once again Russ Nelson's asm packet driver provided additional info.
3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
Too bad it doesn't work -- see below.
The ES3210 is an EISA shared memory NS8390 implementation. Note
that all memory copies to/from the board must be 32bit transfers.
Which rules out using eth_io_copy_and_sum() in this driver.
Apparently there are two slightly different revisions of the
card, since there are two distinct EISA cfg files (!rii0101.cfg
and !rii0102.cfg) One has media select in the cfg file and the
other doesn't. Hopefully this will work with either.
That is about all I can tell you about it, having never actually
even seen one of these cards. :) Try http://www.interlan.com
if you want more info.
Thanks go to Mark Salazar for testing v0.02 of this driver.
Bugs, to-fix, etc:
1) The EISA cfg ports that are *supposed* to have the IRQ and shared
mem values just read 0xff all the time. Hrrmpf. Apparently the
same happens with the packet driver as the code for reading
these registers is disabled there. In the meantime, boot with:
ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
shared memory detection. (The i/o port detection is okay.)
2) Module support currently untested. Probably works though.

lne390.c
Linux driver for Mylex LNE390 EISA Network Adapter
Copyright (C) 1996-1998, Paul Gortmaker.
This software may be used and distributed according to the terms
of the GNU General Public License, incorporated herein by reference.
Information and Code Sources:
1) Based upon framework of es3210 driver.
2) The existing myriad of other Linux 8390 drivers by Donald Becker.
3) Russ Nelson's asm packet driver provided additional info.
4) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
The LNE390 is an EISA shared memory NS8390 implementation. Note
that all memory copies to/from the board must be 32bit transfers.
There are two versions of the card: the lne390a and the lne390b.
Going by the EISA cfg files, the "a" has jumpers to select between
BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
The shared memory address selection is also slightly different.
Note that shared memory address > 1MB are supported with this driver.
You can try <http://www.mylex.com> if you want more info, as I've
never even seen one of these cards. :)
Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/01

- no need to check if dev == NULL in lne390_probe1

ne3210.c
Linux driver for Novell NE3210 EISA Network Adapter
Copyright (C) 1998, Paul Gortmaker.
This software may be used and distributed according to the terms
of the GNU General Public License, incorporated herein by reference.
Information and Code Sources:
1) Based upon my other EISA 8390 drivers (lne390, es3210, smc-ultra32)
2) The existing myriad of other Linux 8390 drivers by Donald Becker.
3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
The NE3210 is an EISA shared memory NS8390 implementation. Shared
memory address > 1MB should work with this driver.
Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched
around (or perhaps there are some defective/backwards cards ???)
This driver WILL NOT WORK FOR THE NE3200 - it is completely different
and does not use an 8390 at all.
Updated to EISA probing API 5/2003 by Marc Zyngier.

/* 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.
