SDHC_HIGH_SPEED bit in SDHC_HOST_CTL, required to get many high speed cards working on rpi

Fixes probing of full-size 1GB Toshiba card made in 2008 that fails to
respond with a 1.8V supply. (JMB389 (in TS-RDF1) host claims
SDHC_VOLTAGE_SUPP_1_8V but does not claim SDHC_EMBEDDED_SLOT.)

Also, add comment to denote an ESDHC bit.

can support one segment per operation. This is not the case with SDHCI SDMA,
the only SDHCI DMA mechanism we currently support in sdhc(4). Should fix
corrupt data on DMA-enabled SDHCI controllers claiming conformance to a SDHCI
Specification other than 1.0.
|
|
it can issue commands, and some host drivers have interrupt-driven
command completion. Prevents assertion (or deadlock) upon detach
of sdhc(4) with inserted card.
|
|
It seems to have caused regressions to detaching drivers from cards at
the appropriate time.
DETACH_FORCE to sdmmc_card_detach really means the SD/SDIO card is gone,
and can not be abused to mean that the host controller disappered.

has support for non-power-of-two divisors from 1 to 1023. Additionally
restore finding the correct power-of-two divisor for standard-compliant
pre-3.0 SDHCI parts. Also, calculate minimum divided clock for the
clkmsk-quirk parts correctly.
XXX Will future standard-compliant SDHCI versions have a SDHCI 3.0
backwards-compatible clock generator, or just SDHCI 1.0/2.0?

segment, the transfer is not implicitly complete; we still need to wait
for the transfer complete interrupt so that we can issue new commands
successfully.
This fixes the problem my Ricoh R5C822 was having where all writes after
a larger (64KiB) write were failing because we attempted to issue CMD13
(to check the status of the aformentioned write) too soon afterwards.
I suspect this fix to apply to other Ricoh SDHCI controllers I've heard
people have had trouble with. Sorry I didn't look at this sooner.

This should make multiple slot controllers, for example those with
a controller on more than one PCI/CardBus BAR, detach with fewer bugs.
Tested with as-of-yet-uncommited sdhc_pci changes on a single-host
ExpressCard JMicron JMB38[89].

host controller has disappeared or is detaching.
XXX should pass flags from sdmmc_detach through to the task thread ending
to differentiate host controller disappearance from mere detachment.

Some of this could/will also be useful for the SD Status register.

instead of just "<PNM>". Probably should figure out a way to stuff this
into the device properties database too, but not everything has
pseudo-device drvctl enabled.
Also, drop trailing whitespace.

and SD_CSD_CSDVER_2_0.

On the AM335x, we first must wait for the controller to acknowledge
the reset; then we can wait for the reset to complete.
I believe this quirk also applies to the OMAP4 ES, but I don't have
one of those to test and we don't seem to have an obvious conditional
for it anyway.
This quirk may work for controllers that don't require it too, but I
am nervous about doing it by default because if we miss the reset
acknowledgement, then we'll just time out even though everything is
really hunky-dory.
Also, for all sdhc, don't bother writing 0 in sdhc_soft_reset while
waiting for the reset to complete; there is no need.

This change makes sdhc_host_found allocate hp up front before showing
the identification, in order to avoid having to open-code a copy of
HREAD2 before hp is available.

While without a large physically-contiguous buffer the performance
suffers severly, this should still be better than PIO.

Additionally, add commented out calculation of actual clock frequency.

As we always want response data in LE, use bus_space_read_stream.
Additonally, read response data in 1 or 4 4-byte chunks, instead of
one 4-byte chunk or 15 1-byte chunks.
