drivers/net: delete 8390 based EISA drivers.
The NS8390 chip was essentially the 1st widespread PC ethernet chip, starting its life on 8 bit ISA cards in the late 1980s. Even with better technologies available (bus mastering etc) the 8390 managed to get used on a few rare EISA cards in the early to mid 1990s. The EISA bus in the x86 world was largely confined to systems ranging from 486 to 586 (essentially 200MHz or lower, and less than 100MB RAM) -- i.e. machines unlikely to be still in service, and even less likely to be running a 3.9+ kernel. On top of that, only one of the five really ever was considered non-experimental; the smc-ultra32 was the one -- since it was largely just an EISA version of the popular smc-ultra ISA card. All the others had such a tiny user base that they simply never could be considered anything more than experimental. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

4 Linux driver for Racal-Interlan ES3210 EISA Network Adapter
5
6 Copyright (C) 1996, Paul Gortmaker.
7
8 This software may be used and distributed according to the terms
9 of the GNU General Public License, incorporated herein by reference.
10
11 Information and Code Sources:
12
13 1) The existing myriad of Linux 8390 drivers written by Donald Becker.
14
15 2) Once again Russ Nelson's asm packet driver provided additional info.
16
17 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
18 Too bad it doesn't work -- see below.
19
20 The ES3210 is an EISA shared memory NS8390 implementation. Note
21 that all memory copies to/from the board must be 32bit transfers.
22 Which rules out using eth_io_copy_and_sum() in this driver.
23
24 Apparently there are two slightly different revisions of the
25 card, since there are two distinct EISA cfg files (!rii0101.cfg
26 and !rii0102.cfg) One has media select in the cfg file and the
27 other doesn't. Hopefully this will work with either.
28
29 That is about all I can tell you about it, having never actually
30 even seen one of these cards. :) Try http://www.interlan.com
31 if you want more info.
32
33 Thanks go to Mark Salazar for testing v0.02 of this driver.
34
35 Bugs, to-fix, etc:
36
37 1) The EISA cfg ports that are *supposed* to have the IRQ and shared
38 mem values just read 0xff all the time. Hrrmpf. Apparently the
39 same happens with the packet driver as the code for reading
40 these registers is disabled there. In the meantime, boot with:
41 ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
42 shared memory detection. (The i/o port detection is okay.)
43
44 2) Module support currently untested. Probably works though.

11 Information and Code Sources:
12
13 1) Based upon framework of es3210 driver.
14 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
15 3) Russ Nelson's asm packet driver provided additional info.
16 4) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
17
18 The LNE390 is an EISA shared memory NS8390 implementation. Note
19 that all memory copies to/from the board must be 32bit transfers.
20 There are two versions of the card: the lne390a and the lne390b.
21 Going by the EISA cfg files, the "a" has jumpers to select between
22 BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
23 The shared memory address selection is also slightly different.
24 Note that shared memory address > 1MB are supported with this driver.
25
26 You can try <http://www.mylex.com> if you want more info, as I've
27 never even seen one of these cards. :)

10
11 Information and Code Sources:
12
13 1) Based upon my other EISA 8390 drivers (lne390, es3210, smc-ultra32)
14 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
15 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
16
17 The NE3210 is an EISA shared memory NS8390 implementation. Shared
18 memory address > 1MB should work with this driver.
19
20 Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched
21 around (or perhaps there are some defective/backwards cards ???)
22
23 This driver WILL NOT WORK FOR THE NE3200 - it is completely different
24 and does not use an 8390 at all.
25
26 Updated to EISA probing API 5/2003 by Marc Zyngier.

1/* smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
2
3Sources:
4
5 This driver is based on (cloned from) the ISA SMC Ultra driver
6 written by Donald Becker. Modifications to support the EISA
7 version of the card by Paul Gortmaker and Leonard N. Zubkoff.
8
9 This software may be used and distributed according to the terms
10 of the GNU General Public License, incorporated herein by reference.
11
12Theory of Operation:
13
14 The SMC Ultra32C card uses the SMC 83c790 chip which is also
15 found on the ISA SMC Ultra cards. It has a shared memory mode of
16 operation that makes it similar to the ISA version of the card.
17 The main difference is that the EISA card has 32KB of RAM, but
18 only an 8KB window into that memory. The EISA card also can be
19 set for a bus-mastering mode of operation via the ECU, but that
20 is not (and probably will never be) supported by this driver.
21 The ECU should be run to enable shared memory and to disable the
22 bus-mastering feature for use with linux.
23
24 By programming the 8390 to use only 8KB RAM, the modifications
25 to the ISA driver can be limited to the probe and initialization
26 code. This allows easy integration of EISA support into the ISA
27 driver. However, the driver development kit from SMC provided the
28 register information for sliding the 8KB window, and hence the 8390
29 is programmed to use the full 32KB RAM.
30
31 Unfortunately this required code changes outside the probe/init
32 routines, and thus we decided to separate the EISA driver from
33 the ISA one. In this way, ISA users don't end up with a larger
34 driver due to the EISA code, and EISA users don't end up with a
35 larger driver due to the ISA EtherEZ PIO code. The driver is
36 similar to the 3c503/16 driver, in that the window must be set
37 back to the 1st 8KB of space for access to the two 8390 Tx slots.
38
39 In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
40 be a limiting factor, since the EISA bus could get packets off
41 the card fast enough, but having the use of lots of RAM as Rx
42 space is extra insurance if interrupt latencies become excessive.
