f9097dce5d pcmcia: remove irq_list parameter from pd6729
Remoe the irq_list parameter from pd6729, as it can and should be set
via sysfs (and -- if available -- pcmciautils, which reads the information
from /etc/pcmcia/config.opts )

f3d4ae431d yenta_socket: ENE CB712 CardBus bridge needs special treatment with Echo Audio Indigo soundcards
Indigos are well known for distortions when running on some buggy ENE
controllers.  There is a workaround in the yenta driver, but for some
reason it isn't activated on CB712.  However, I own a laptop with such
chip and it seems that it also is affected - I can clearly hear occasional
cracks, especially under heavy network load, and in Windows XP the card is
completely unusable.

This simple change fixed things for me.

11b897cf84 MIPS: Alchemy: use 36bit addresses for PCMCIA resources.
On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus
area.  Currently, addresses at the far end of the 32bit area are assumed
to belong to the PCMCIA area and fixed up to the real 36bit address before
being passed to ioremap().

A previous commit enabled 64 bit physical size for the resource datatype on
Alchemy and this allows to use the correct 36bit addresses when registering
the PCMCIA sockets.

This patch removes the 32-to-36bit address fixup and registers the Alchemy
demo board pcmcia socket with the correct 36bit physical addresses.

Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet
card.

66213b3ccf MIPS: PCMCIA: new socket driver for Au1000 demoboards.
New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000),
which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c.
Notable improvements:
        - supports Db1000, DB/PB1100/1500/1550/1200.
        - support for carddetect and statuschange IRQs.
        - pcmcia socket mem/io/attr areas and irqs passed through
          platform resource information.
        - doesn't freeze system during card insertion/ejection like
          the one it replaces.
        - boardtype is automatically detected using BCSR ID register.

Run-tested on the DB1200.

9bdcf336d0 MIPS: Alchemy: devboard register abstraction
All Alchemy development boards have external CPLDs with a few registers
in them.  They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.

This patch
- adds a primitive facility to initialize and use these external
  registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
  functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
  headers in a central place.

7b4884ca88 pcmcia: validate late-added resources
Currently, only those mem resources are validated which are already
registered at the time the first PCMCIA card is inserted. As we can
only validate resources immediately after card insert, store
"registered" mem resources in mem_db, and only upon validation move
them to mem_db_valid. When allocationg mem resources, mem_db_valid is
then preferred to mem_db.

89a74ecccd PCI: add pci_bus_for_each_resource(), remove direct bus->resource[] refs
No functional change; this converts loops that iterate from 0 to
PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the
pci_bus_for_each_resource() iterator instead.

This doesn't change the way resources are stored; it merely removes
dependencies on the fact that they're in a table.

a7eb169dc7 pcmcia: m32r uses static socket resources
m32r_cfc sets the socket capabilities to SS_CAP_STATIC_MAP and
also sets io_offset != 0. This means no calls to
&pccard_nonstatic_ops went through. Therfore, replace it with
&pccard_static_ops which is exactly for this case.

385ee87109 pcmcia: remove useless indirection
As release_resoure_db() used to be called only from one place, and
it's a two-line function, remove it.

3970dd8c51 pcmcia: do not lock socket driver module on card insert
Do not lock the socket driver module on card insert, as
the PCMCIA core can handle a socket module removal, at least
if we add a call to socket_remove() on pccardd()'s shutdown.

593f010bc0 pcmcia: do not lock socket driver module in pcmcia_get_socket()
Do not lock the socket driver module in pcmcia_get_socket(), as
the PCMCIA core can handle a socket module removal: In
pcmcia_unregister_socket(), we explicitely wait for the last
put_device() to succeed.

3f32b3c093 pcmcia: rsrc_nonstatic io memory probe improvements
Add a lot of documentation to the rsrc_nonstatic io memory probe
functions. Also, add a first memory probe call -- just checking
whether request_resource() succeeds -- upon adding of resources.
