The sdmmc_chip_write_protect callback returns the write protect switch
status from the controller (SDWP#). This signal does not exist for eMMC;
instead, write protect is signaled using card registers (CSD). So lets
skip asking the chipset for WP status on eMMC cards for each write
request.

Defer power save setting to interface start.
More verbose on errors.
Allow build without FDT.

The Arasan SDHCI 8.9a found in the Xilinx Zynq-7000 SoC requires this
sequence to avoid sporadic transfer errors.

ADMA2 support in sdhc is mature now, so no need for it to be opt-in.
|
|
the clock_bus pre- and post- callbacks used in sdhc_bus_clock_ddr()
are called with a spin mutex held, and the new sdhc@acpi ends up
calling into (sleeping) ACPI code, triggering lockdebug assertion.
introduce an adaptive mutex that is held around these callbacks,
and reduce the spin mutex held time in sdhc_bus_clock_ddr().

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Don't enable autostop when command sets new flag SCF_NO_STOP.

rename of_search_compatible() to of_compatible_lookup().
Standardize on of_compatible_match() for driver matching, and adapt
all call sites.

Add diagnostic messages.

Like disk_begindetach, ldbegindetach only commits to detaching but
doesn't wait for existing xfers to drain; it is up to the driver to
abort them, once we are committed, and then ldenddetach to wait for
them to drain.

this removes the final hard hang i have seen in pinebookpro wifi,
though one may still need to 'ifconfig bwfm0 down up' occasionally,
so we still have bugs to fix here (the hang is usually associated
with 'checksum error' from bwfm/sdio.)

interrupts, not all of them. we only ack these ones.
mostly fixes pinebookpro wifi hard hangs. still is problematic and can
trigger interrupt storm that appears as a hard hang without NET_MPSAFE,
and a follow up, less clearly right, change will reduce that to a soft
hang of the interface that can be cleared with 'ifconfig bwfm0 down up',
and even often recovers itself now.

- Teach sdmmc_add_task to queue it only if not already queued.
- Remove now-redundant logic to avoid repeated queueing elsewhere.
- Teach sdmmc_del_task to wait until task has completed.
- Call sdmmc_del_task in various needful places.
- Replace abuse of pcq by a lock and a tailq.
(pcq is multi-producer, _single_-consumer, but there are potentially
multiple consumers here and really only one producer.)
- Teach ld_sdmmc to abort xfers on detach.
(Mechanism is kinda kludgey but it'll do for now; any effort one is
tempted to spend overhauling this should be spent overhauling sdmmc
to support proper asynchronous commands.)
- Make sure ld_sdmmc_discard either returns failure or eventually calls
ldenddiscard.
XXX Currently ld_sdmmc_detach aborts xfers _before_ ldbegindetach has
has committed to detaching or not. This is currently necessary to
avoid a deadlock because ldbegindetach waits for xfers to drain --
which strikes me as wrong; ldbegindetach shouldn't wait for anything,
and should only make the decision to commit to detaching or not so
the caller can decide whether to abort xfers before we actually wait
for them in ldenddetach.
XXX pullup -- although this changes some kernel symbols (sdmmc_add_task
and sdmmc_del_task), it shouldn't affect any existing modules; the only
module that uses sdmmc is ld_sdmmc.kmod, which is `.if 0' in the build
so there shouldn't be any of them floating around.

setting this but continue with other settings. This allows us to use
a card, albeit at a lower speed.

core driver that understand how to find model-specific files before the
generic files. This greatly simplifies the firmware loading procedure
in each of the bus front ends. Adding additional firmware file types
(such as CLM files) much simpler.
- Make firmware image selection table-driven rather than a set of switch()
and if() statements.
- Add several additional firmware image entries.
