Here is an uptodated version of the MPC8xx PCMCIA driver for v2.6,
addressing comments by Jeff and Dominik:
- use IO accessors instead of direct device memory referencing
- avoid usage of non-standard "uint/uchar" data types
- kill struct typedef's
Will submit it for inclusion once v2.6.14 is out.
Testing on 8xx platforms is more than welcome! Works like a charm
on our custom hardware (CONFIG_PRxK).

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

In interrupt probing (both ISA and PCI) the bridge control register is used
to change interrupt routing to ISA or PCI by changing bit 7. But this bit
only controls the routing of card functional interrupts, not the CSC
interrupts which are used for interrupt probing.
A bad side effect of messing with this register in yenta_probe_irq() is
that it can lead to irq storms if a card is inserted and already powered by
the BIOS.
Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

Echo Audio cardbus products are known to be incompatible with EnE bridges.
in order to maybe solve the problem a EnE specific test bit has to be set,
another cleared...but other setups have a good chance to break when just
forcing the bits. so do the whole thingy automatically.
The patch adds a hook in cb_alloc() that allows special tuning for the
different chipsets. for ene just match the Echo products and set/clear the
test bits, defaults to do the same thing as w/o the patch to not break
working setups.

In some cases, especially on modern laptops with a lot of PCI and
cardbus bridges, we're unable to assign correct secondary/subordinate
bus numbers to all cardbus bridges due to BIOS limitations unless
we are using "pci=assign-busses" boot option.
So some cardbus controllers may not have attached subordinate pci_bus
structure, and yenta driver must cope with it - just ignore such cardbus
bridges.

multifunction cards need to have the same irq assigned to both functions.
the code tries that but fails because ret is still set to CS_IN_USE which
results in the function having the CB irq assigned. yenta_set_socket then
just changes the irq routing to use the PCI interrupt but the first
functions irq handler is registered on an ISA interrupt. boom.

Share code between setup-bus.c and yenta_socket.c: use the write-out code of
resources to the bridge also in yenta_socket.c, as it provides useful debug
output. In addition, it fixes the bug that the CPU-centric resource view

while yenta-socket.c did not.

ToPIC95 brides (and maybe some other too) require to use the ExCA registers
to power up the socket if a 16bit card is pluged. allow socket drivers to
set a flag so that yenta does just that. also clean up yenta_get_status()
a bit to use the new yenta_get_power() function.
Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this.
Ryan Underwood <nemesis-lists@icequake.net> said:
According to the mail that David Hinds received from a Toshiba engineer,
ToPIC95 and 97 do require this, and ToPIC100 does not. Maybe you have a
later revision.
For all chips, 16-bit cards can be enabled through ExCA. So doesn't it
make sense just to make this the default behavior for all Toshiba chips,
to avoid corner cases showing up later?
Daniel responded:
I disagree with ryan to change anything for topic97 bridges. they work.
and I couldn't find (read google) any report of a topic97 breaking on
applying power with the CB registers.
I'm having several toshba notebooks at work (and home) with topic95,97,100
bridges. Only the ones with a topic95 didn't work.

In yenta_socket, we default to using the resource setting of the CardBus
bridge. However, this is a PCI-bus-centric view of resources and thus needs
to be converted to generic resources first. Therefore, add a call to
pcibios_bus_to_resource() call in between. This function is a mere wrapper on
x86 and friends, however on some others it already exists, is added in this
patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where
is its pcibios_resource_to_bus() ?).

Recent changes (well, dating from 12 July) have broken cardbus on my
powerbook: I get 3 messages saying "no resource of type xxx available,
trying to continue", and if I plug in my wireless card, it complains
that there are no resources allocated to the card. This all worked in
2.6.12.
Looking at the code in yenta_socket.c, function yenta_allocate_res,
it's obvious what is wrong: if we get to line 639 (i.e. there wasn't a
usable preassigned resource), we will always flow through to line 668,
which is the printk that I was seeing, even if a resource was
successfully allocated. It looks to me as though there should be a
return statement after the two config_writel's in each of the 3
branches of the if statements, so that the function returns after
successfully setting up the resource.
The patch below adds these return statements, and with this patch,
cardbus works on my powerbook once again.

ACPI is wrong. Devices should not release their IRQ's on suspend and
