Get rid the of most local macro wrappers for consistency. The ones which
make sense for readability are renamed to X86_MATCH*.
In the centrino driver this also removes the two extra duplicates of family

get_mode() is used to retrieve the active mode state. Settings-A
config is used during active state, whilst Settings-B is for
suspend. This means we only need to check the sleep field of each
buck and LDO as that field solely relates to Settings-A config.
This change is a clone of the get_mode() update which was committed
as part of:

struct partition is the on-disk format of a MSDOS partition table entry.
Move it out of genhd.h into a new msdos_partition.h header and give it
a msdos_ prefix to avoid confusion.
Also move the magic number from block/partitions/msdos.h to the new
header so that it can be used by the SCSI drivers looking at the DOS

There is no good reason for __bdevname to exist. Just open code
printing the string in the callers. For three of them the format
string can be trivially merged into existing printk statements,
and in init/do_mounts.c we can at least do the scnprintf once at
the start of the function, and unconditional of CONFIG_BLOCK to
make the output for tiny configfs a little more helpful.

The controller needs a valid bus voltage in its power register
regardless of whether an external regulator is taking care of the power
supply.

sdhci_set_power_and_bus_voltage(), so create a bcm2711 specific 'struct
sdhci_ops' which makes use of it.

Tegra host supports HW busy detection and timeouts based on the
count programmed in SDHCI_TIMEOUT_CONTROL register and max busy
timeout it supports is 11s in finite busy wait mode.
Some operations like SLEEP_AWAKE, ERASE and flush cache through
SWITCH commands take longer than 11s and Tegra host supports
infinite HW busy wait mode where HW waits forever till the card
is busy without HW timeout.
This patch implements Tegra specific set_timeout sdhci_ops to allow
switching between finite and infinite HW busy detection wait modes
based on the device command expected operation time.

When SDHC gets reset (E.g. in runtime suspend path), CQE also gets
reset and goes to disable state. But s/w state still points it as CQE
is in enabled state. Since s/w and h/w states goes out of sync,
it results in s/w request timeout for subsequent CQE requests.
To synchronize CQE s/w and h/w state during SDHC reset,
explicitly deactivate CQE just before SDHC reset.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

The Spreadtrum host controller supports HW busy detection for commands with
R1B responses, but also for I/O operations. This means when the host gets a
transfer complete event, that always indicates the busy signal is released.
Let's inform the mmc core about this, via setting the corresponding
MMC_CAP_WAIT_WHILE_BUSY flag, as to remove some redundant software busy
polling.

Currently, when use standard tuning, driver default disable DMA just before
send tuning command. But on i.MX8 usdhc, this is not enough. Need also clear
DMA_SEL. If not, once the DMA_SEL select AMDA2 before, even dma already disabled,
when send tuning command, usdhc will still prefetch the ADMA script from wrong
DMA address, then we will see IOMMU report some error which show lack of TLB
mapping.

On i.MX8MM, we are running Dual Linux OS, with 1st Linux using SD Card
as rootfs storage, 2nd Linux using eMMC as rootfs storage. We let the
the 1st linux configure power/clock for the 2nd Linux.
When the 2nd Linux is booting into rootfs stage, we let the 1st Linux
to destroy the 2nd linux, then restart the 2nd linux, we met SDHCI dump
as following, after we clear the pending interrupt and halt CQCTL, issue
gone.
