considerably easier, and is based on Chuck Cranor's original patch for 4.6.

o rework pll setup code to follow h/w specification
o add hint.hifn.X.pllconfig to specify reference clock setup
requirements; default is pci66 which means the clock is
derived from the PCI bus clock and the card resides in a
66MHz slot
Tested on 7955 and 7956 cards; support for 7954 cards not enabled
since we have no cards to test against.

Rather than have a twisty maze of special case allocations, move
instead to a data driven allocation. This should be the most robust
way to cope with the resource problems that the multiplicity of ways
of encoding 5 registers that have the misfortune of not being a power
of 2 nor contiguous.
Also, make it less impossible that pccard will work. I've not been able
to get my libretto floppy working, but it now fails later than before.
phk and I had similar ideas on this during the 5.3 release cycle, but
it wasn't until recently that I could test more than one allocation
scenario.

producers rather than consumers as new-bus resources only handle consumed
resources. We already do this for the other ACPI resource types that
support the producer/consumer attribute.

For such devices, we require _PRS to exist and we warn if any of the
resources in _PRS are not IRQ resources (since we'll have no way of knowing
which of those resources to use without a working _CRS). When it does
come time to set resources, we build up a resource buffer from scratch
as we do for devices with _CRS that only have IRQ resources.
- Fix a bug with setting extended IRQ resources where we set the IRQ value
in the wrong resource structure meaning that whichever IRQ was listed in
_PRS was used instead. This might fix some weird issues on certain boxes
where IRQs > 16 don't seem to work when using ACPI.
- Fix a bug with how we walked the resource buffer after _SRS to call
config_intr() in that the 'end' variable was not properly updated, so we
could either terminate the loop early or loop after the end of the
buffer.

o correct the max scatter/gather count; it cannot be larger than the

for the vast majority of our cards. However, they are critically
needed to distinguish different fe based PC Cards (the FMV-182 from
the 182A) which need to be treated differently (the ethernet address
is loaded not from the standard CIS-based ethernet tuples, but from
differing locations in attribute space based on the version string in
CIS3. This should have no impact for other users of this function.
- Introduce the amr_io_lock to control access to command queues, bio queues,
and the hardware.
- Eliminate the taskqueue and do all completion processing in the ithread.
- Assign a static slot number to each command instead of doing a linear
search for free slots each time a command is needed.
- Modify the interrupt handler to more closely match what Linux does, for
safety.
