It appears that some vendors provision the boot areas with valid part
tables (GPT) in order to have identifiable partitions for device and
firmware specific data, such has the qualcomm CDT (Qualcomm Config
Data Table). Additionally, these boot areas can be utilized to host
device-specific IDs, calibration data, and other critical information.

ACMD22 is used to verify the previously write operation. Normally, it
returns the number of written sectors as u32. SDUC, however, returns it
as u64. This is not a superfluous requirement, because SDUC writes may
exceeds 2TB. For Linux mmc however, the previously write operation
could not be more than the block layer limits, thus we make room for a
u64 and cast the returning value to u32.

The SDUC spec expects CMD22 to get squeezed between CMD23 and the
read/write command, e.g. CMD23->CMD22->CMD18 and CMD23->CMD22->CMD25.
At this early stage of adoption, we want to avoid an amid stream of
fixes & quirks of bogus hw, that tends to apply extra logic specifically
around auto-cmd12 & auto-cmd23.
Let's leave close-ended out for now, and re-consider this should those
cards become ubiquitous, if any.
It also means that BLK_FEAT_FUA will not be used for I/O, but instead we
will rely on BLK_FEAT_WRITE_CACHE.

Move the cache control settings into the queue_limits so that the flags
can be set atomically with the device queue frozen.
Add new features and flags field for the driver set flags, and internal
(usually sysfs-controlled) flags in the block layer. Note that we'll
eventually remove enough field from queue_limits to bring it back to the
previous size.
The disable flag is inverted compared to the previous meaning, which
means it now survives a rescan, similar to the max_sectors and
max_discard_sectors user limits.
The FLUSH and FUA flags are now inherited by blk_stack_limits, which
simplified the code in dm a lot, but also causes a slight behavior
change in that dm-switch and dm-unstripe now advertise a write cache
despite setting num_flush_bios to 0. The I/O path will handle this
gracefully, but as far as I can tell the lack of num_flush_bios
and thus flush support is a pre-existing data integrity bug in those
targets that really needs fixing, after which a non-zero num_flush_bios
should be required in dm for targets that map to underlying devices.

Field Firmware Update (ffu) may use close-ended or open ended sequence.
Each such sequence is comprised of a write commands enclosed between 2
switch commands - to and from ffu mode. So for the close-ended case, it
will be: cmd6->cmd23-cmd25-cmd6.
Some host controllers however, get confused when multi-block rw is sent
without sbc, and may generate auto-cmd12 which breaks the ffu sequence.
I encountered this issue while testing fwupd (github.com/fwupd/fwupd)
on HP Chromebook x2, a qualcomm based QC-7c, code name - strongbad.
Instead of a quirk, or hooking the request function of the msm ops,
it would be better to fix the ioctl handling and make it use mrq.sbc
instead of issuing SET_BLOCK_COUNT separately.

Userspace has currently no way of checking the internal R1 response error
bits for some commands. This is a problem for some commands, like RPMB for
example. Typically, we may detect that the busy completion has successfully
ended, while in fact the card did not complete the requested operation.
To fix the problem, let's always poll with CMD13 for these commands and
during the polling, let's also aggregate the R1 response bits. Before
completing the ioctl request, let's propagate the R1 response bits too.

SPI doesn't have the usual PROG path we can check for error bits
after moving back to TRAN. Instead it holds the line LOW until
completion. We can then check if the card shows any errors or
is in IDLE state, indicating the line is no longer LOW because
the card was reset.

The error checks in mmc_blk_add_debugfs() and mmc_blk_remove_debugfs()
are extraneous. Therefore, this patch removes all error checks from
both functions.
Additionally, mmc_blk_add_debugfs() has been changed to return void
instead of an integer value that was never used. This simplifies the
function and improves its clarity.

Requests to the mmc layer usually come through a block device IO.
The exceptions are the ioctl interface, RPMB chardev ioctl
and debugfs, which issue their own blk_mq requests through
blk_execute_rq and do not query the BLK_STS error but the
mmcblk-internal drv_op_result. This patch ensures that drv_op_result
defaults to an error and has to be overwritten by the operation
to be considered successful.
The behavior leads to a bug where the request never propagates
the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if
mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then
can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged)
and thus may assume that their call executed successfully when it did not.
While always checking the blk_execute_rq return value would be
advised, let's eliminate the error by always setting
drv_op_result as -EIO to be overwritten on success (or other error)

Let's align to the common busy polling behaviour for mmc ioctls, by
updating the below two corresponding parts, that comes into play when using
an R1B response for a command.
*) A command with an R1B response should be prepared by calling
mmc_prepare_busy_cmd(), which make us respects the host's busy timeout
constraints.
**) When an R1B response is being used and the host also supports HW busy
detection, we should skip to poll for busy completion.

The workaround of pretending R1B non-data transfers are data transfers in
order for the busy timeout to be respected by the host controller driver is
removed. It wasn't useful in a long time.
Initially the workaround ensured that R1B commands did not time out by
setting the data timeout to be the command timeout in commit cb87ea28ed
("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an
if-clause with idata->buf_bytes being set in commit 4d6144de8b ("mmc:
core: check for zero length ioctl data"). Since the workaround is now
inside the idata->buf_bytes clause and intended to fix R1B non-data
transfers, that do not have buf_bytes set, we can remove the workaround
altogether. This was dead code, since data transfers doesn't use R1B
commands.

Before switching back to the right partition in mmc_blk_reset there used
to be a check if hw_reset was even supported. This return value
was removed, so there is no reason to check. Furthermore ensure
part_curr is not falsely set to a valid value on reset or
partition switch error.
As part of this change the code paths of mmc_blk_reset calls were checked
to ensure no commands are issued after a failed mmc_blk_reset directly
without going through the block layer.

Some SD-cards from Sandisk that are SDA-6.0 compliant reports they supports
discard, while they actually don't. This might cause mk2fs to fail while
trying to format the card and revert it to a read-only mode.
To fix this problem, let's add a card quirk (MMC_QUIRK_BROKEN_SD_DISCARD)
to indicate that we shall fall-back to use the legacy erase command
instead.
