b023c93005 Don't set the number of SCBs here. aic7xxx.c determines the number of
SCBs by walking them.

76e002c102 3c5x9.c:
The eisaconf probe for the 3Com 3c579 and the 3c509 when in eisa
configuration mode.

aha1742.c aic7770.c bt74x.c:
Only call eisa_registerdev after the probe is successfully.

eisaconf.c:
Increase kdc->kdc_datalen during the eisa_reg* functions instead of
in the eisa_add* functions since eisa_registerdev has already been
called and we have a kdc to manipulate.

- Call eisa_registerdev as soon as we have a device match.  This allows the
   "eisa_add_*" routines to tweak kdc_datalen as the kdc grows and shrinks.

eisaconf.c
 - externalize the linked lists that hold our ioaddrs and maddrs.

b18d8f49f2 Another pass through eisaconf. Ioaddrs and Maddrs are link lists now.
The Bt driver is the only one that actually registers multiple addresses.

Probe output is formatted to 80 columns.

dad30388b2 The long awaited stability patch set for the aic7xxx driver:
aic7770.c:
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.

eisaconf.c:
outb 0x80 instead of 0xc80.  The top byte is truncated anyway, and 0x80
was what was intended.

932c2f65d3 Second pass on this. Sentinal device node was an uneeded complication.
Handle kdc registration correctly.  Catch ISA devices that use eisa
registration and output probe information accordingly.

lsdev will have to be updated to handle EISA devices correctly.

aic7770.c:
	Set kdc_isa0 as the parent for 284X cards since its a VL card.

ffd34a3d43 This is a totally new implementation of eisaconf. It will hopefully
be the beginning of our move to a more dynamic (configuration manager)
based setup for all drivers.  Everything seems to work except for
some devconf problems.  Only the aic7xxx driver will be using this
interface until it is reviewed, revised and accepted as a good configuration
interface.

Adapt aic7770.c to use new eisaconf.

eisadevs.c is replaced by a linker set.

6b172e59a6 First pass cleanup of this driver. This pass does not include the sequencer
optimizations I have been working on yet, but does bring in some bug fixes
and performance improvments that were easy to regression test:

Setup the data fifo threshold and bus off timing correctly for 27/284x cards.
Users of these adapters with fast periferals (greater than 5MB/s) will notice
a big performance difference. (Sometimes as large as going from 3.7->8.3MB/s).

Fix handling of the active target flags.  Some of the outbs where missing
the base offset in the abort code.  The abort code still needs lots of work.

Support 3940 controllers, but only with 16 SCBs for now.  Eventually I'll
add support for all 255, but I need to find a tester for the code first since
we have to enable the cards external SRAM to do this.

Add Dan Eischen's serial eeprom reading facilities.  This allows the 2940
adapters to pull additional information left over from SCSI-Select right out
out of the configuration seeprom.

If the BIOS is disabled on 274x controllers, reset all target parameters
to there defaults since you can't rely on what is stored in scratch ram.

Report motherboard controllers as such.

Stick the first SG address and count into the SCB data and count areas for
all transfers in preparation of a later sequencer optimization.

Keep track of which targets can are allowed to have the disconnection
priveledge since this will be handled by the kernel driver in the future.

If a target issues a message reject in response to a tagged message,
disable tagged queuing for that target.  Some seagates say they can do
tagged queuing, but lie, and its a shame to have to disable tagged queuing
on all devices just because you have one that can't cope.

6c0081e92b Add a class field to devconf and mst drivers.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago).  For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device.  The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out.  A few bytes saved by using
%b to format the features list rather than lots of ifs.

53a69701bc Handle both channels of Twin channeled devices. Respect the configuration
values for syncronous negotiation.  The 284x series adaptors can now be
supported without the Bios being enabled.  If you disable the Bios on the
274x series adaptors, all configuration parameters revert to the default
since there is no way to retrieve them.
